Adding to my Case: the fact that sometimes I feel like everyone else on the internet is some kind of damn genius. This guy worked out how to make a sequencer using paper, skittles and a webcam. The webcam picks up where the skittles are placed, and somehow software translates each position to a different drum sound. Moving the pieces around makes different patterns of different instruments.
Weird science.

On his Vimeo page, the author says:
Future directions may include: more sensor types (e.g., a slider for tempo control), note-sequencing mode, and assigning the different colors to different rhythms or instruments (purple as bassline, or yellow as "every other measure").
There is a cut in the middle where it transitions from solo improvisation to three people interacting simultaneously. Any out-of-sync audio/video is due to my frazzled camera.
One of the other big problems: people like to eat Skittles.
