Metope-Rebird Unofficial music video by Matthias Dörfelt
The video was entirely programed in c++, OpenGL and glsl using openFrameworks. No other software used.

Simple Harmonic Motion
When I saw this beautiful video - http://www.youtube.com/watch?v=yVkdfJ9PkRQ&feature=player_embedded - I wondered what the sonic equivalent would sound like. The oscillation frequencies of each pendulum is described on the webpage so putting this demo together and keeping it accurate to the original video was relatively straightforward.
made in processing, using themidibus library to send midi to Ableton Live

Also check out Steve Reich (e.g. most of his early work using ‘phasing’ - though technically what’s happening in the video above is not exactly ‘phasing’), Norman Mclaren (e.g. horizontal / vertical lines series), Gyorgi Ligeti (e.g Poeme Symphonique for 100 metronomes), and of course Ollie Williams from Family Guy http://www.youtube.com/watch?v=bg4-AtqhKh8
and many many more.
UPDATE: As an exercise in supercollider (which I’m just learning), i tried to recreate the audio element, and it sounds so much better (the timing is a lot tighter, unsurprisingly). Here is the code for that:
{o=0; 15.do{|i| o=o+LFTri.ar(138.59*(1.0595**(3*i)), 0, LFPulse.kr((51+i)/60, 0, 0.05, 0.1))}; o;}.play;
Note the sounds in the video above are NOT from supercollider. They are triggered from the processing sketch as midi notes sent to Ableton Live. The notes in the processing sketch are selected from a pentatonic scale. I wanted the supercollider code to fit in single tweet ( less than 140 chars), so I omitted the scale and instead pick notes which are spaced at minor 3rd intervals, creating a diminished 7th arpeggio. The base note is C#. Toccata and fugue in d minor anyone?

MoMu is a light-weight software toolkit for creating musical instruments and experiences on mobile device, and currently supports the iPhone platform (iPhone, iPad, iPod Touches). MoMu provides API’s for real-time full-duplex audio, accelerometer, location, multi-touch, networking (via OpenSoundControl), graphics, and utilities. The MoMu Toolkit was developed as part of the Mobile Music research initiative in Music, Computing & Design group at Stanford University’s CCRMA, in collaboration with Smule. MoMu is released under a BSD-like license; while not required, we’d love to know how you are using MoMu in your research and products! Email us!
Color Code
Color Code allows anyone to program using colors in the real world. The result is that you can program a computer or a robot, or compose a musical score, just by drawing on a piece of paper with crayons. Of course it’s not limited to crayons. You could build your program with Lego bricks, arrange your program with the multi colored leaves of early Fall, or think of any collection of objects in the world as a program: from a striped shirt to a handful of M&Ms. In the limit, several interesting new programming concepts emerge from this paradigm: commands are no longer discrete and rigid but mixable and smearable; the program counter becomes visible, handheld, and nondeterministic; and when the color sensor becomes the program counter the application space and the programming space become intertwined.

creat atmospheric computer sounds
Be careful of your ears, this app can produce wild sounds at high volume. Program this sound synthesis puzzle machine by dragging letters TOPLAp to the grid; you can also set a parameter for each position via the slider at each slot. The audio engine whizzes through the states many times per second. Press ! to clear the grid, and ? to randomise. No save or load is allowed, to promote improvisation.
