Blue Monster
Sean Bogg’s Blue Monster contains a very slowly rotating spiral full of googly eyes, inside a ring of blue monster fur. As it rotates, the eyes shift, in their sockets in a charming and alarming way! Here’s a link to Sean’s page, where you can see a movie of the artwork in action.
I found this on Dustyn Robert’s site, Making Things Move, a subject which is currently occupying my spare cycles as I attempt to build a MIDI-controlled bell choir. Dustyn’s site is full of awesome maker projects that involve movement of various kinds.
I liked Sean’s piece so much that I made a simplified version of it in Processing, which you’ll find on my Processing blog, Joy of Processing.
