I found this off the Make: blog. Its a perfect post-gluttonous interlude for your thanksgiving. Combine the trance-like music with a heavy dose of tryptophan you got from gorging on turkey all afternoon and it makes for a rather interesting psychedelic trip.
"Flowers" by Jan van Nuenen.
Apparently the whole performance was created "using a Monome controlling Ableton Live via a max/msp patch called boiingg." If you have any idea what the Hell any of that means, you should really check out the Make site for all the electronic details.
