For my final project, I created an interactive audio visual mixer using the song Shelter by Porter Robinson and Madeon. There are four different display settings that the user can choose from. Pressing the corresponding keys will load animations that correspond to parts of the song. There are three functions called “Interject” that display image oriented animations while the function “Beat” displays pulsing ellipses that coincide with the beats of the song.

The main issue I had was embedding the audio file and having it load properly so I opted to link the file instead of it having it play automatically.

Enjoy!

Isabella Hong – Final Project Proposal

For my final project, I want to create an audiovisual mixer like Daito Manabe’s “Arigato Skating.” In his production, Manabe used cameras to capture the movement of the junior skaters on the ice and used projectors to project visuals on to the ice in line with the movements. In the end, it looked like twinkling lights and lines were emerging from the skaters’ blades as they performed on the ice.

My idea is to have shapes and patterns emerge from the user’s mouse. The different objects that will be drawn as the mouse moves will depend on the song’s (which I have yet to choose) current rhythm. This way, the visual is in accordance to the audio, hence an audiovisual mixer.

These are some preliminary sketches and ideas that I have for the audio and visuals. They will become solidified once I choose the exact portion of one of the songs I have in mind.

Isabella Hong – Looking Outwards – 12

For my last Looking Outwards post, I will be comparing and discussing the works of interaction designers, Daito Manabe and Caitlin Morris.

Daito Manabe is an artist, programmer, and DJ based in Tokyo, Japan. As a designer, he focuses on the relationship between the body and programming, opting to represent the connections in simple, clean works. He enjoys finding the balance between simple and intricate in his productions and this shows in his work, “Arigato Skating”, a motion graphic made for the opening of the NHK Trophy (a stop on the figure skating grand prix circuit). By using projectors and cameras, Manabe created the illusion that the junior skaters were creating lines of light and flowers with their blades. The full production is beautiful.

http://www.daito.ws/en/work/2012-nhk-trophy-arigato-skating.html

Caitlin Morris is an artist and technologist that explores various representations of physical space often through sound and perception. She is constantly crossing the line between digital and physical space, testing where the limit is on both. In November of 2010, Morris did a sound installation on the Brooklyn Bridge that demonstrated this flirtation with digital and physical interaction. She installed contact microphones across the railings of the Brooklyn Bridge. When pedestrians plugged their headphones into the little boxes, they could hear the vibrations of the bridge, indirectly interacting with the bridge’s interaction with water, wind and travelers. It was very cool.

A pedestrian listens to the Brooklyn Bridge

Although both Manabe and Morris are interaction designers, their works delve and trigger reactions from different senses. Manabe focuses on the visual and tactile interaction between his art and his audience. Meanwhile, Morris focuses on how her audience can interact with sound. Overall, both artist provoke reaction through their productions, something that I think is crucial when presenting personal work.

Isabella Hong – Project 11 – Composition

For the composition project this week, I decided to attempt to create an abstract rendering of a rose. To start with, I looked at the properties of Turtle Graphics that we had learned and implemented last week and began my project.

Here is what it looked like throughout the process of creating my “rose petals.”

screen-shot-2016-11-11-at-7-22-57-pm

In the process of creating my rose petals

‘I found that when I was incrementing by numbers larger than one, I was getting the desired density in the center of my graphic, essentially the center of the flower. When I switched my incrementation to i++, I got the exact look I was going for – a heavily filled in center that spiraled outwards to create a beautiful abstract rose.

Here’s the final result:

For this week’s post on sound art, I chose to focus on Sound Machines, an instrument that was created for performing electronic music. Sound Machines was unveiled in 2011 for Volkswagen at the reveal party for the then new Beetle.

The device itself is composed of three different standard looking record players that are synced to an additional sequencer. The three discs each track a different sound. The visual patterns on the discs were produced manually by “reverse engineering” the music that had been customized for the event itself. The tracks were then controlled by the softwares Arduino and Processing.

I admire that The Product, the Berlin based creators of the device, took into consideration the music itself when designing the device. It adds a personal touch and connection. In addition, the SoundMachines was only the beginning – The Product wants to take it one step further and implement the device at music festivals in the future.

Isabella Hong – Looking Outwards 10

For this week’s post, I decided to focus on designer, educator, and creator Rachel Wingfield. Wingfield attended the Royal College of Art and studied responsive environments that are inspired by living systems. Her concentration in school is still evident in the work she has produced throughout her professional career.

In 2003, Wingfield founded Loop.ph, a crafting space and laboratory that focuses on incorporating living materials and technology into public environments. As the founder of Loop.ph and as a designer, researcher and educator, Wingfield encourages designers and the public to intervene on an urban scale, to turn living materials into visual experiences and environments.

A project that incorporated these fundamentals was Brainwaves: Faster than Sound. The project was done in collaboration with Loop.ph, the contributing artists being Wingfield, Mathias Gmachl, Professor Vincent Walsh, Mira Calix, Anna Meredith, and The Aurora Orchestra, Joana Seguro – Lumin. The installation was constructed of dead trees that were arranged into a highly intricate grid of electro-luminous strings that worked in tandem with the positions of the musicians in the space. While the musicians performed, MRI images and slices of Malthius’ skull would be projected, demonstrating the intricacies of neural functions in action.

img_9842a — An example of one of many projections

I particularly admired this project for it’s unique output – the final installation incorporated biology, music, and technology to create this immersive and very futuristic experience. I think that what Wingfield is doing as an artist is constructing a bridge between science, technology, and the arts even further.

Isabella Hong – Looking Outwards -09

I am doing my Looking Outwards post on Hannah K’s post from Week 4. She did a post on Six Drawings, a joint collaborative effort between artist Maotik, percussionist David Espinosa, and musical director David Adamcyk. The project was presented in an audiovisual and instrumental performance at Société des Arts Technologiques in Montreal during the IX Symposium in the spring of 2014. The displays on the rubber orb were controlled through the program TouchDesign while the connected computer ran a Max multimedia software.

I also agree that the work is a completely immersive experience. When the first sounds are visually displayed on the giant orb, the room becomes silent and everyone is enraptured and fascinated by the erie, almost tribal, audiovisuals. One simply cannot peel their eyes away.

At Eyeo 2015, Samuel Sinyangwe and Deray McKesson spoke on the topic of racial justice and activism in addition to how they’ve utilized social media to spread awareness of what goes on in the news each day. For this post, I chose to focus on Singyangwe.

Samuel Sinyagwe in an American policy analyst and racial justice activist that currently resides in San Francisco, California. He is the co-founder of WetheProtestors, an organization that provide people with a platform to end police violence in their local communities. Sinyagwe studied racial intersections within the United States in the realms of politics, economics, and class. He describes himself as an activist that works with affected communities.

I admire Sinyagwe for his calm yet active approach to tackling the issue of racial injustice. He isn’t angrily aggressive, he’s actively progressive and constantly working to give people agency. He embraces the community and helps them initiate change.

Sinyagwe is an articulate and charismatic speaker that understands the power of employing a group for change. He shows the audience that there is evidence, real and tangible statistics of racial injustice, clearing the fog around where racial injustice is concentrated. It’s not – it’s everywhere and that’s why Sinyaqwe does what he does.
