RAP1 is a special purpose computer built to study lattice gas models. It allows the simulation of any model using less than 16 bits per node, and interactions restricted to first and second nearest neighbors on a square lattice. The time evolution of the automaton is displayed in real time on a color monitor at a speed of 50 frames per second.
