Sound Boards

Modulate your voice to create boards in real time. Size is based on volume and color is based on pitch. Then they drop onto a spinning circular saw that slices them. Using OpenFrameworks and ofxBullet for the physics.

Scream Splode

Over inflate using your voice until it bursts. The louder the noise, the bigger the explosion. In this recording, made it a lower volume to burst since screaming into the screen was causing the sleeping baby to stir.

Audio Cleaners

Creating noise balls with my voice. Audio cleaners come and keep the area tidy.

Pitch Draw

Moving particles with sound. Pitch of my voice controls direction, color and size; volume influences speed. A 440 Hz would be perfect straight velocity…clickity clack of the keyboard.


An interactive visual experiment for the track Deserve by Bruzed. Live input mode allows the user to play any audio with limited visuals. Download the OSX application via the download link below.


Based on past experiences, I decided not to submit to the Mac App Store. You may have to change your preferences to use the application. System Preferences > Securty & Privacy > Allow Applications Downloaded from > Anywhere








Bass Shapes

Bass Shapes is a stand-alone computer application that is visually stimulated by audio input. Three dimensional primitives are generated and react to the beat of the music using 3d physics. The app was originally intended to be available on the Mac App Store. The app was rejected by Apple who gave the reason “it is not very useful.” Apple suggested adding more features to the app including “multiple scenes/themes, strobe lights, blurring, etc.” The suggestions opposed the original aesthetic, concept and goals, so I decided to release the app for free download for OSX here:

I created these sketches for the Tribeca Film Festival Interactive Day. Unfortunately I didn’t get too much documentation at the actual event. But there are a few photos below and a video of me interacting with the app. The compression kills the quality of this video, please watch in HD if you can.

Audio Reactive Worm

This is an audio reactive visualizer that is based on a previous experiment about representing audio through sections of a worm’s body. The goal was to get the worm to look similar to black glass. The large worm’s body is divided into 11 sections that represent the FFT analysis data. When the corresponding group of frequencies surpasses a certain threshold, that section of the worm becomes lighter in color, the surrounding rings become lighter, the radius of that section becomes larger and particles are emitted from the surrounding rings. Once the particles have been emitted, they fade, change color and become larger over time, while reacting to large changes in the beat. The large worm explores the empty space. On large beat hits, it will hurry forward and if a major song change is detected, may even do a choreographed move, like a spiral or zig-zag. The large worm is followed by many smaller, simpler worms that flock along its body. They change color and repel from the worm body on large beats hits. The light scattering effect in the background reacts to the audio, becoming more prominent on louder beats and it also changes color over time or due to dramatic changes in the audio.
