Margot's Other Cat: Kinetic Sculpture by Arthur Ganson

In "Margot's Other Cat" a soaring chair is set in random motion by an unsuspecting cat.  The cat's motion is utterly stationary while the chair in a predetermined random way jumps over it.

The notes accompanying the YouTube video states:

"This machine was inspired by watching a randomly shaped object bouncing off the surface of a slow moving, reciprocating and irregularly shaped piston head on the moon. Of course anything is possible in the virtual world of the computer.

The doll house chair seems to be the perfect object to bounce nearly weightlessly over the unsuspecting cat. In this machine, the chair is passive and all motion is due to interference by the cat. The large disk at the back serves to both counterbalance the arm and give more mass to the chair itself. The motion of the chair is complex and will never repeat."

If you, as I, marvel at the pure genius of Ganson's creative engineering prowess, then you may like to hear him talk about his work and process.
