Another 1000 of things; cars hanging on the wall, turning on occasionally, trying to move, and falling back, than resting again. A real (handmade) urban tapestry.
The cars are controlled by six Arduino chips designed by Massimo Banzi. One acts as server and the others as clients. The controlling program can be downloaded as arduino code (server / client) or as pdf (server / client), the latter also containing code colours.
