For my final project, I wanted to show that climate change is not just a singular concept, but rather a buildup of many different factors and situations, as well as how they are related to one another. First, trees are cut down to clear space for more buildings, people in these buildings require electricity which requires the burning of fossil fuels, and the release of carbon dioxide into the air exacerbates global warming and melts glaciers that increase ocean levels.

The user goes through these 3 scenes and interacts with them, worsening the situation. At the end of each scene, they are presented with statistics of each action and they realize those consequences. Perhaps the polar bear is a metaphor for humans and at the end when the polar bear “drowns”, the user is asked “Are you sorry now?” telling them to rethink their actions before it is too late.

If I had more time, I would have liked to make my graphics more detailed. I would have also liked to include sound but I was having too many problems with looping the sounds so I decided not to include them.

For this project, I made 2 fish who are lovers that swim randomly around an aquarium looking for each other. When they meet, they fall in love again and the supportive crab in the corner claps for them and a love song plays.

For this project, I wanted to create an interactive portrait. I was inspired by Ryan Alexander’s work and wanted to have the portrait show up based on where you clicked your mouse. I wasn’t able to get that working fully, but I still think the final product is pretty cool as the way the portrait shows up changes based on where you click the mouse. I also added randomness to each pixel width and height to make the portrait more animated.

For this week’s Looking Outwards, I wanted to talk about Vera Molnar, who is regarded as a pioneer of computer generative art and is one of the first women artists to use computers in her practice. Particularly, I was drawn to her piece “(Dés-)Ordres”. What caught my eye initially were the contrasting colors used in different parts of the image, pulling my eye around. This contrast between order and disorder amongst the different layered squares also creates the impression of movement as if the squares are vibrating against one another. Surprisingly, this image was generated with a computer, where Molnar changed the parameters of her algorithm to randomly disrupt the regularity of the concentric squares.

Molnar was born in Hungary in 1924 and studied art history and aesthetics at the Budapest College of Fine Arts. From as early as 1959, she began experimenting with the concept of algorithms or “machine imaginaire” where an image can be created by following a set of pre-ordained compositional rules. In 1968, she begin using computers and plotters to make her paintings and drawings, creating a variety of algorithms iterating simple geometric shapes and geometrical themes.

Mike Tucker is an interactive director, designer, and developer who has been working at Magic Leap for the past 5 years. I was inspired by his spatial computing projects and even more so after his lecture at EYEO. I am personally very interested in the fields of AR and VR and how they can change the human experience. While he started his career with graphic design, he seems to be more interested in combining music with interactive digital environments. The project he presented at EYEO 2019: Tonandi, was especially interesting to me because of all the different senses incorporated into it. Including sight, sound, and motion, it is amazing how immersive digital environments can be designed nowadays. The lecture itself was effective in showing the actual experience of using the headset Magic Leap designed. Tucker presented videos showing live demos of the VR projects and how the user can interact with the virtual environment. The videos are also shot from a first-person perspective so the viewer can see the project as if they are using the VR headset themselves.

For this project, I was excited to explore different types of curves and how you can create new ones through simple interactions. I started off my process by looking at and trying different curves in Sublime to see which ones were the most interesting to change. I also spent some time plugging mouseX and mouseY into different parts of the equation to see how they changed. I found it interesting that curves can look completely different based on which variables were changed. For instance, I used a Cayley’s Sextic curve for one of my curves, which looks like a rounded heart. However, when you control the ratio multiplied by cosine, it changes the number of curves and their rotation so it looks like a flower.

Astroid curve in different phases:

A student in CMU Design called Bryce Li created a website in 2021 that helps visualize songs by a specific artist. If you like a song by that artist, the website can show you other songs by the same artist that are similar. This information is presented in clustered data points that are visualized as circles. Each circle represents a song and the closer 2 circles are together, the more similar those songs are. When you click on a circle, it also plays a 30-second clip of the song so you can hear it for yourself. This website was coded using libraries from React and Three js. And the coding languages are HTML, CSS, and JS. To cluster different points by shared similarities, Spotify has a quantifying API that Bryce used along with a k-means clustering algorithm. I thought this was interesting because I often come across a similar situation where I like an artist’s song but I don’t know how to find similar songs. By simplifying the amount of data a user sees and taking away unnecessary information, this website, therefore, communicates clearly what the user wants to know: similar types of songs by the same artist.

I started off this project by sketching a rough idea of what I wanted to make, which was two people playing badminton, with the shuttlecock moving from one end to the next in minutes. The sun and moon would then rotate according to the hour.

original sketch

However, I came across some coding problems so I changed my idea slightly. Now, they are aliens that can only move with every minute. As they move closer to each other, they are waving and their eyes follow each other. While I kept the sun and moon concept the same, I changed the background clouds to increase numbers according to seconds.

For this week’s LO, I looked back on a game I used to play a lot as a kid: Minecraft created in 2011 by Mojang. It is interesting how despite its simple graphics, Minecraft encourages creativity and worldbuilding. This shows that games do not need the most sophisticated or detailed assets to still be fun and addicting. One of the main defining aspects of Minecraft is its terrains that are regenerated with every game and are virtually infinite, allowing the player to explore and build however they wish.

I was curious about how the terrains were generated, as they seemed to spawn randomly, sometimes even creating floating islands. Apparently, Minecraft terrains are generated based on Perline noise functions. When the game starts, it generates a Seed (a random 64-bit number) which is used to generate noise functions. So the game starts on a broad level by creating simple topographical maps, then goes into smaller random details like bushes, animals, lakes, etc. However, these random environments and objects still have a consistent logic and constraints they have to follow to make them believable terrains. This random generation allows for a different world each time, giving the player new ideas and possibilities to define their own gameplay.

Before creating this wallpaper, one of my friends from home called me and showed me pictures of her cats. In the spur of the moment, I thought that it’d be cute to create a wallpaper full of cats. I also thought it would be cool if the wallpaper could generate different versions of itself. For this, I created 3 different cats and had the draw function choose a random cat to draw each time it ran through the 2 for loops. For each cat, I drew up a quick sketch of what I wanted each cat to look like and added some decorative yarn and butterflies to make them look more like wallpaper:
