The latest kinetic sculpture from Chris Cole, called Velouria, features a guitar amplifier hidden in the base. When you crank the sculpture, the metallic fish like comes to life. In addition, various ports are open and close which affects the sound coming from the amplifier.
From the YouTube description:
This piece was inspired by the Pixies song and will be part of the "Dig For Fire" show at C.A.V.E. Gallery in Venice California Sept 9-October 1, 2011.
Sounds like an interesting show! There is more on this sculpture at Chris Cole's web site.
