Youphonium #1

Youphonium #1 is a toy you can use to create live experimental music. To play with it, you need a camera and two colored objects to hold up to the camera. Run it in a large browser window, click "START CAMERA", and follow the built-in directions. Be sure to turn up the main volume slider gradually, as some settings can damage your speakers or your hearing.

You can use all of Youphonium #1's features with just the built-in directions and trial-and-error experimentation. If you want more information about the audio synthesis settings, you can optionally also download the technical reference document. 

All of the video processing happens locally in your browser. Youphonium #1 does not send any of your information over the Internet.
