Katamari-Like Giant Ball of Monitors and Cameras.

Jonathan Schipper built this ball from 215 closed circuit surveillance camera and 215 monitors, called "215 Points of View."

As he rolls the 5.5 foot diameter ball with 800 pound mass of steel, glass, and electronics around, the images displayed on each monitor is actually transmitted from a camera from the opposite side, thus making it seems like the viewer is looking through an invisible ball.
