REDGREEN

REDGREEN is an update to RUBE, written in ALPACA. Unlike RUBE, it is a proper cellular automaton, not a bully automaton. As such, its description is much cleaner and its behavior is easier to predict, while it retains most of the "feel" of RUBE.

Computational class
REDGREEN contains John Conway's Game of Life cellular automaton as a subset within it, and Life has been shown to be Turing-complete; thus, REDGREEN should also be Turing-complete.
