^ I know, right?! I've gotta do something like that next time I trip. Which reminds me of another cool idea for a techy trip toy I read about - you hook up a microphone to a computer (or you just use the built-in mic if you've got a Mac), then you open up a DAW program, create an audio track, send the audio input to the track's input, add a bunch of crazy insert effects (delays, flangers, bitcrushers, etc.), then put the track on "monitor" mode - and bingo, crazy psychedelic alteration of the audial component of your environment. %)
edit: that was supposed to be in response to Cosmic Charlie.
