We spotted this cool project on Kickstarter:

The Syntheshredder is an interactive installation utilizing live sound and performance. It’s a 20ft diameter skate bowl that will house sensors embedded under the surface. These will then be routed to a series of hardware instruments as well as custom software that will effectively turn the ramp into a versatile musical instrument. By transforming the skater into the musician, the Syntheshredder will have the potential to generate sounds and layered compositions that I believe will be quite powerful and compelling. Along with several musicians and artists, we will produce several tracks which will be pressed onto a limited edition run of 12″ vinyl records.
