Our show is centered around The Four Seasons, a series of four violin concerti composed by Antonio Vivaldi. The show is characterized by an opening that provides a brief introduction of the four seasons, and then the next four parts are each devoted to a specific season in the order of spring, summer, fall, then winter. Finally, the outro and closing is meant to thematically summarize the show as a whole. In the musical composition, each concerti is designed to characterize the feelings and themes of each corresponding season. Furthermore, each season has a corresponding sonnet with which the music also goes along to. These themes are represented for each of the seasons in our show through the utilization of a variety of visual characteristics such as color, movement, speed, etc.

Introduction: The show begins with the bridge being segmented into four different parts with each one representing a season using the primary color of the season. Then, a very brief synopsis of what each season will bring is presented in order before transitioning into the main show.

Spring: Spring is characterized by a time of budding flowers and the rising sun. The colors and movement are meant to represent a carefree spring morning. The scene below shows the budding of the flowers with each block representing a flower slowly fading in.

Summer: Summer has a faster tempo and a higher level of intensity, but also contains instances of slowness to represent scenes such as a gentle summer breeze. The scene below represents of the intense moments, with rapidly changing blue lights to show the scene of a torrential downpour.

Fall: Fall generally has a more carefree and cheerful rhythm to represent the coming and celebration of the harvest. Pastel oranges, reds, and browns are used to express the beauty of autumn leaves. The scene blow contains alternating orange lights to represent a festival, where everyone is moving about and celebrating, and spirits and activity are high.

Winter: Winter transitions into a darker, more sinister melody as well as gentleness with snowy days. The scene below shows the northern lights, with the same colors and gentleness of an aurora that would be seen in the sky.

Outro: After the conclusion of winter, there is a short fadeaway, and then it breaks into a short summary of each of the four seasons. Then, each of the seasons are briefly shown all together before the show fades away completely.

This will be a display that follows the story of a young, ordinary farmer’s journey of becoming a hero to save his beloved. His journey through different landscapes and seasons, as well as the arcs of the story will be shown through the lights and the actions on the bridge.

There are 10 scenes in the display:

  • Start off at a farmland, lush and amazing spring
  • Walking through a dark forest
  • Wading through the river
  • Navigating through the hot desert
  • Braving the tough flurry snow
  • Traveling through mountains in the winter
  • Running through the fantastical forest. Breezy, full of motion.
  • Exploring the dark dangerous dungeon
  • Fighting the dragon. Intense colors and quick motion
  • Celebration and joy at the end. Ending off with the fireworks

Mathematical Sequences https://courses.ideate.cmu.edu/15-661/s2021/2547/mathematical-sequences/ https://courses.ideate.cmu.edu/15-661/s2021/2547/mathematical-sequences/#respond Fri, 07 May 2021 00:35:45 +0000 https://courses.ideate.cmu.edu/15-661/s2021/?p=2547 Continue reading Mathematical Sequences ]]> Team Members: Alia Friedman, Ariel Uy, Hiroshi Wu, Jessica Xiao, Joshua Cheng

Our show features a visual presentation of five mathematical sequences: Perfect Squares, Pi, Fibonacci Sequence, Prime Numbers, and the Pythagorean Theorem. While mathematical sequences are inherently numerical, the visualization of these sequences and their proofs can be quite beautiful. Therefore, we not only present the sequences themselves, but also an explanation of the mathematical concepts behind each sequence. Mathematics is very important to computer science, engineering, and many other fields, and we think that CMU students would appreciate this display. We hope that our display will bridge both the artistic and technical communities at CMU.

Part1: Perfect Squares

The first part of the show exhibited the number-line format of perfect squares, where we count towards each square. However, the beauty of perfect squares reveals itself when all the numbers are shown on a square and the perfect squares form a diagonal. We emphasize this beauty by eventually showcasing how the numbers gradually build from the side and middle and expand outwards at every step.

Part2: Fibonacci Sequence

The second part of the show illustrates the Fibonacci sequence along the span of the bridge, with each number in the sequence being represented by the spacing between the distinct orange panels. The orange panels light up gradually from left to right, representing the concept of growth associated with the Fibonacci sequence.

The Fibonacci sequence can be found in many real-world applications such as art and nature. Therefore, we sought to represent these concepts through the background colors, using a Python script to automatically generate the background colors from images of art and nature. This result in an interesting blend of colors that complemented the distinct orange panels.

Part3: Pythagorean Theorem

First discovered in ancient Greece, the Pythagorean Theorem can be used to find the hypotenuse of a right triangle using the two other sides.

In this section of the show, the number of light panels represented a and b. The numbers were then squared and the panels corresponding to those numbers were illuminated. The numbers were then amount added together and their colors were also blended in order to arrive at C^2. The number’s square root was then taken and the corresponding amount of panels were illuminated. In the picture above we can see nine panels being added to 16 panels, in order to arrive at 25 representing a side C of five.

Part4: Prime Numbers

Prime numbers are the building blocks of the integers, and they are an important part of many areas of mathematics and computer science. In this section of the show, the prime numbers are visualized using the Sieve of Eratosthenes, which is a simple method to derive the primes. The bridge itself is a number line from Gates to Purnell. First, all multiples of 2 are colored purple, then all multiples of 3 are colored blue, and so on, leaving only the prime numbers in bright white. The visualization brings a pattern and a motivation to the prime numbers.

Part5: Pi

Pi is integral to our world; wherever a circle exists, pi exists. I tried to show how pi integrates in a few scenarios, such as unravelling a circle, and in sine wave oscillations. These are both represented as moving lights on the bridge. Pi is also an interesting transcendental number in that no patterns have been found in the decimal representation, so it’s a good source of randomness, which I exhibited as colorings of the bridge. Overall I hoped to show both the structural and chaotic aspect of Pi and how that integrates in the world, and the hidden beauty in both structure and chaos.

Introduction to Our Project:

“Working in cross-disciplinary teams, students will explore light as art, interactive design, and programming using a Pharos lighting control system.  Students will explore the use of light and interaction using the actual controls within the Randy Pausch Memorial Bridge.  Student teams will develop final projects that will be exhibited on the Randy Pausch Memorial Bridge.” [Source: Syllabus 15/62-661]

Our short mission: We wanted to create a project that represented our school backgrounds, identities, and interests which is how we chose the story of Persephone and Hades. We appreciated the different and complex interpretations of the story and found it the ideal creative avenue to use to create a bridge installation – due to the story’s timelines and its dramatic themes.

Main Tools Utilized:

|Figma – For Brainstorming and Visual Conceptualization | Google Slides – For Presentations and Critiques |Pharos Lighting Control System – For the light installation|

Premise

Our show follows the Greek legend of Persephone and Hades. 

At its core, the story is an explanation for the seasons. Hades, god of the underworld, falls in love with the goddess Persephone and kidnaps her. While in the underworld, Persephone eats the seeds of a pomegranate, which prevent her from being able to return to the surface. Her mother, Demeter is devastated by the loss of her daughter and prevents crops from growing in her grief. Finally, Zeus, king of the gods, works out a compromise in which Persephone will return to her mother for a portion of the year, and spend the remainder with Hades. And so the reunion of Persephone with Demeter each year marks the beginning of Spring, while her departure brings Winter.

Being a myth, the story has many slight variations in how the events are presented, and our group was drawn to versions of the story where Persephone embraced her role as queen of the underworld, rather than simply being a damsel in distress. In the show, we focus on Persephone’s growth from innocence to maturity, driven by her struggle as she is torn between two worlds.

Planning:

Before diving into creating our actual show, we began by brainstorming colors and schemes to represent the different characters and settings for our show. Below, are a few examples of mood boards where we used reference images in order to create a color palette for our settings and characters.

The most important aspect of selecting colors was assigning them to our main characters. We settled on the following colors to represent our main characters:

  • Persephone: Purple
  • Hades: Blue
  • Demeter: Gold

Additionally, for our characters Zeus and Hermes we decided to use whites, golds, oranges, and reds and rely on the movement of light to depict their existence and actions, rather than just a solid color.

Part One: The Garden

Our show begins with a slow-paced depiction of a garden, represented by a bright green background with light blue and light pink panels, or “flowers”, slowly blooming in and out of the scene. The gates end of the bridge has blue and white flickers, simulating water in a pond. The blooming stops and a purple streak slowly moves back and forth across the bridge, depicting Persephone strolling through the garden and enjoying the flowers. Eventually, she stops at a dark blue flower and an orange-red fiery flicker effect spreads out from where Persephone and the blue flower are. The blue flower is meant to represent the presence of Hades, and when Persephone stops at this flower, she is kidnapped and the scene takes a rapid change to the fast-paced Underworld. 

Part Two: The Underworld

We transition into a scene depicting the Underworld and chose to emphasize the relationship between Hades and Persephone. After introducing the setting through the most commonly known symbol of the Underworld, fire, we go through several fast-paced scenes of interwoven pinks, purples, and blues dancing across the bridge. The shade of purple darkens throughout this scene, representing the growing maturity of Persephone as she interacts with Hades and the Underworld. Alternatively, the shade of blue lightens as Hades grows softer through his interactions with Persephone.

Part Three: The Drought

There is once again a shift in pace as we transition to the state of the Earth in the absence of Persephone. In contrast to the fast pace of the Underworld, the drought scene is still and devoid of bright colors. The previous garden scene is replicated but this time, all of the colors are desaturated and the barely visible flowers slowly disappear. This scene emphasizes the despair of Demeter as all life on Earth seemingly disappears. 

Part Four: The Deal

The next scene for our show is when Zeus sends Hermes down to the Underworld to retrieve Persephone in order to stop Demeter’s drought. Zeus and Hermes are depicted in Olympus, within the clouds. As Zeus tells Hermes to travel to the Underworld, they exchange colors a number of times to represent their interaction. Hermès then descends to the Underworld shown on the Gates side of the bridge, while the clouds of Olympus fade away and the bridge transitions to the flickering footprints of Hermes.

Part Five: The Pomegranate

The bridge is split in half to show the underworld and overworld side-by-side. On opposite extremes of the bridge, Demeter and Hades both reach out for Persephone who flushes between dark and light shades of purples as she feels torn between the two worlds.

Persephone finally reaches out to Demeter and begins ascending from the underworld. But separating them is a red pomegranate. Persephone flickers with darkness as she thinks of Hades and her life in the underworld, and she decides to consume the pomegranate seeds, knowing that they will compel her to remain in the underworld. Darkness rushes in as she falls back to the Underworld and reunites with Hades. However, because she ate only six of the pomegranate seeds, she is able to return to the surface for half of the year. 

Part Six: Seasons

Seasons Part One:

In order to show the pattern of how Persephone’s arrival to Earth brings spring and her departure brings winter, we created a setting where the Gates end of the bridge represents the Underworld and the rest of the bridge represents Earth. Persephone is shown exiting the Underworld and making her way across Earth, transforming the drought into the bright green garden scene shown earlier. She is then shown returning to the Underworld and leaves behind a scene of icy colors. This pattern is repeated twice in order to show the circularity and repetitive nature of the seasons. 

Seasons Part Two: In this part, we show the cyclical nature of the seasons as we know it now.

We start off in winter, where it’s cold, but despite that, Hades and Persephone are enjoying the time they have together before spring comes. The bright green wave background behind them is the aurora borealis, a fair representation of their passion despite it being winter, something that is usually correlated with bleakness. 

As the wave of pink comes, representing spring, we see Hades disappear, and Persephone chases after him, not wanting it to end. Demeter (golden yellow) then comes in and comforts her, and reminds her that she isn’t alone, and they walk off the “stage” together. Persephone is the goddess of spring, so we wanted to showcase her powers with a gradient of pink and purple, representing flowers. In the middle of spring, a bit of Hades calls out in the distance, and Persephone once again misses him, causing it to rain (April showers).

Summer comes in to comfort, and we see Persephone and Dementer enjoying their time together in the sun. They walk on “stage” together and then start weaving around each other, showing a more playful nature and a healthy mother-daughter relationship. In the background, we can see the leaves slowly change into autumn colors.

Autumn comes in with a flickering effect, acting as leaves falling. Persephone and Demeter depart, and Hades and Persephone reunite. This celebration is shown through them weaving together. The bridge then lights up with their colors, showing a happy ending.

Reflection and Recommendations:

Our team ran one trial show before the final presentation on last Thursday May 6th. In this trial run, we realized that darker colors do not lend themselves well to creating a compelling light show due to the fact that the luminosity is not strong or vibrant enough to be seen. Due to this our team brightened the spectrum of colors we decided to use –so that the colors could be seen up close and from afar.

In our final show our colors and transitions were dazzling and bright, showcasing the story of Hades and Persephone and how they evolved and how ultimately our season came into existence. We did notice that certain parts of the show could have been a bit brighter but we were satisfied with the results.

Some recommendations we would give anyone programming the bridge is to:

  • Choose bright colors that show up on the bridge
  • Test the color show multiple time and from various viewpoints and angles of the bridge
  • Utilize Pharos creatively and always push for the most innovative display.
  • Have a cohesive story from end to finish – most people who will see your bridge installation will most likely not understand the context -so it is important to have some color story or drama in your performance that captivate the viewer.

Thank you to:

This show focuses on the effects of global warming on the world and how sustainability practices can be used to solve the issues. As environmental conservation and safety become significant concerns, we were drawn to understanding the dire consequences through a new lens of a light show. Elements like water, fire, winds, light have been combined to form recurring motifs in this artistic display of environmental change.

  • Act 1: This show would start with colors representing a healthy world, before the start of global warming (greens, blues etc.).  The main symbols incorporated here include the northern lights, sunrises, oceans, and more. The rhythm is more or less stable in this section to represent the harmony of life.
  • Act 2: The next part of the show would focus on the negative impact of global warming, with the temperature rising, increased pollution etc (red, orange, grey etc.). The main symbols incorporated here include the forest fires, floods, heavy downpour, and pollution. The pace is often suddenly quickened to highlight the disruption of equilibrium brought on by the onset of global warming.
  • Act 3: Finally the show ends on a positive note, signifying hope for the future if sustainability practices (clean energy, sustainable technology, and increased human responsibility) are followed. The act focuses on a meadow scene with blooming flowers that portray the notion of rebirth. Elements of rhythm and tempo of the lighting will be involved while showing the ‘response’ of nature that retaliates.
