Another HTML5 experiment from earlier in the year: generative audio in the browser, just to see if it could be done. It requires FF 4+/Chrome 10+/Safari 6+, so apologies if you can’t see/hear anything in your puny retro browser.
Move red dot with mouse. Click elsewhere to toggle view. Built with Processing.js + PureData.js. Design blatantly ripped from Fonografiks.
Lots more HTML5 stuff (with source code) over at 100 Abandoned Artworks.
