Update october 22, 2013:
This is now an official Chrome Experiment!
What is it?
With the advent of version 6, Safari has implemented WebAudio, making it useable on mobile devices running iOS 6 such as iPads. Having a consumer appliance with a touch screen supporting this technology creates a very interesting field for experimentation.
As such, the resulting experiment is a (multi)touch enabled synthesizer. By creating movable nodes with very exact frequencies, a creative user can coax all manner of other wordly sounds, and perhaps, find an instrument within their hands.
Want to see it?
You can run the experiment here, note that either Google Chrome or Safari 6+ is required.
