Visual Scratch: Live laptop visualization of scratching

Peter writes – “For anyone who checked out my webcam-to-scratching (or other music control) project in Make 04, Jesse Kriss has a new project that’s sort of like the reverse. He’s built a custom patch in the open source software Processing that translates live scratching on a turntable to real-time visuals. Very cool, and you could use the same idea to accomplish many other kinds of projects; the Ms. Pinky control record he uses has been employed in everything from custom, vibrating furniture to art installations involving tree trunks.” – Link.
