Saw "Strange Brew" on video.
Idea: piano goes into laptop.
Distortion filter into a square wave,
and maybe lo-pass it a bit.
Pipe this through two resonators,
and mix them; the resonant frequency
of the two is controlled by mouse position
(maybe with wacom tablet)
It would be nice if I could get the pressure
of the tablet pen, but it doesn't seem
very feasible with Perl/Tk right now.
Maybe I should buy a mike at radio smack.
