Violin Bow - with Color Interface

From the Cal Arts blog 24700 comes a post about students experimenting with instrumental interfaces as part of an exchange program. The description of the violin caught my eye:

"Haraldsdottir, a violist, and myself, a violinist, worked on building interfaces that incorporated an accelerometer and buttons with our bows. Haraldsdottir’s controls allowed for live looping and various audio effects, and my controls consisted of real-time alteration of filter effects and varied response of color intensity in RGB LEDs (lights)."




One wonders what they could have done with a gyroscope on the violin bow...
