First glider discovered in a cellular automata on an aperiodic tiling!

Adam P. Goucher:

It works on the Penrose P3 tiling, made of rhombi. It uses the fact that the sides of rhombi are parallel to guarantee it never gets trapped in a loop. This version has 4 states and uses the Moore neighborhood (vertex-neighbors).

Inspired by the work of Nick Owens and Susan Stepney.
