The Firefly
Constructed at the Swiss Federal Institute of Technology in Lausanne by Moshe Sipper and his colleagues, the Firefly machine is an FPGA-based hardware implementation of a cellular automaton which modifies its functioning dynamically. The system is based on the cellular programming approach, in which parallel cellular machines evolve to solve computational tasks. (Image taken by Andre Badertscher; courtesy of Dr. Moshe Sipper.)
