[sdiy] Foot-stompin' music (idea wanted)

[Theo]

I was to say "sensor paint" a paint you can use to make your pressure
sensitive array any way you want.
But their site is gone, maybe they are out of business :(

Ok another idea, microphones or other vibration sensors (piezo "buzzers") on
the four corners of your foot-stompin stage.
Difference in amplitude and/or phase is a measurement for the place where
you put your feet.
Sum of the amplitude is a measurement for velocity.

Wait a moment, you want to trigger with your feet right?
How about odor-sensors? ;^P
