Kenny Marshall's "prototype for an infinite array of semi-autonomous percussive devices"

Kenny Marshall has portfolio full of interesting kinetic work. He describes his prototype for an infinite array of semi-autonomous percussive devices as being:

... a group of small robotic sculptures, each connected to its immediate neighbors via wires, that together form a net of robotic life that spreads across the Garden at the Mattress Factory and over nearby structures. These twenty-five mechanical crickets fill the garden with sound as they listen to their neighbors and act accordingly during Pittsburgh's Robot250 festival. Using Dr. John Conway’s rules for The Game of Life, each robot activates when a preset number of his neighbors is active and deactivates if too few or too many of his neighbors are active.

The Game of Life is an interesting simulation of simple life that been a favorite of geeky-types since 1970. Worth checking out (if you're a geeky-type).
