As a student who works in the IDEATE space at CMU, I have really come to appreciate some of the creativity around our own University. A sonic art piece that comes to mind is in the stairwell of the Hunt library. A search on the Internet renders not much more than the name of this installation – “Acrylic plastic Ambient auditory experience”, but this product is cooler than it sounds. Using hanging light fixtures that extends from the top of the stairwell to the bottom, it responds to the sound of footsteps on the stairs and lights up the piece of the fixture closest to the sound. I really enjoy this interaction, and I think it’s a creative way to make such a boring space feel exciting and alive. It was created to emphasize the area of the library where you are allowed to make sound. In the publishing of this blog post, I have found more information about the piece – it was created by Jaime Chu and Robert Rudolph. Using clear acrylic, the designers were able to achieve and interesting floating lightbulb effect. See here:

For this project, I really wanted to test out how curvatures can warp lines into creating new dimensions. I also tried to emphasize the depth by using gradients.
Project 04 – String Art
I chose to create a responsive string art project, since I still haven’t had my fill of mouseX and mouseY data use. I also used a mousePressed function to spice things up as well, ultimately changing the location of the pivot points of the string as well as the color.

The color, repetitive nature, string-like-ness, and “stretchy” behavior of this interaction remind me of the rainbow loom. Therefore, I have titled this piece “Rainbow Loom”.
LO – 04 : SOUND ART
François Quévillon’s “Algorithmic Drive” is a project that I personally found to be very interesting. This project is an interactive installation that was inspired by cars and dash cams. It began with François collecting a large database of recordings from a camera attached to his car’s computer. The data collected includes information on location, orientation, speed, temperature, stabilitiy, etc. This data is fed into a sampling system that uses signal processing, data analysis, and computer vision algorithms that then begins to sort the content statistically. The information is mapped using a Uniform Manifold Approcimation and Projection dimension reduction technique.
This project was interesting to me because it utilizes data and information that surrounds us in our daily life, but is then used to create something new and creative.

LO 04 – Sound Art
Milkdrop is a visualizing plugin created by Google employee Ryan Geiss for Winamp, a media player for Windows systems. Milkdrop turns input audio such as songs or movies into abstract, constantly-changing psychedelic compositions. Since its release in 2001, Geiss has added extra features into the plugin, such as pixel shaders that allow for more complex and layered visualization presets.
Milkdrop takes the wavelength of an audio file playing in Winamp and analyzes it to create a visualization based on a preset, which is like a template for the program to convert the wavelength into a visual. Milkdrop uses a grid system on screen in which it calculates a pixel’s value based on a preset and interpolates the other pixels based on these values. In other words, it will calculate the values of about 32 x 24 evenly spaced points on the screen and averages the others based on the calculated values.
I was drawn to Milkdrop from how different it looked from other audio visualizers and how unlimited the potential for creating visualizations based in the program could be. I also found it interesting that Geiss’s skillset translated over to his work at Google, where he currently works on AI software for Pixel phones to help it take better photos.
Looking Outwards 04 – Sound Art
Urban Lights Contacts is an interactive sound and light installation by Scenocosme (Grégory Lasserre & Anaïs met den Ancxt). The installation is composed of a small interactive sphere. When a person puts his or her hand on the sphere, the body turns reactive and sensitive to other living bodies. When the person touching the sphere has a physical contact with another person, the installation starts emitting sounds. Each contact of each person generates varieties of different sounds. What this installation is doing is sensing the body’s electrostatic energy and emitting them as sounds. What’s interesting and unique about this installation is that it creates a sensory interactive experience with what we cannot detect in the eye. Encouraging people to have interactive contacts with other people they don’t know also gives a total unique experience. The interactive device generates a very sensitive approach of the body, recognizing different degrees of electrostatic contacts according to the proximates of living bodies. What I find interesting is that different people produce different electrostatic energy, which also makes the installation emit different sounds as well. The artists of this installation really focus on the interactive experience, an experience people cannot see but can hear and feel through the installation.
