THIS IS WHERE YOUR DEMO GOES is my aborted attempt for this year's js1k competition. It uses the browser's speechSynthesis capabilities along with some Web Audio API drones to make a lovely bedtime song...
I don't think I'll get it squashed to < 1k in the next few days though, so plopping it up here for posterity. The source is buried in the middle of the js1k shim somewhere. Just search for "THIS IS WHERE YOUR DEMO GOES".
