Suggestion: Use Golly to break out of the traditional
Life framework by offering a hexagonal grid as an
option in addition to the usual square grid.
There are three ways of tiling an infinite plane with a
single regular polygon (of a single size): 1. Squares;
2. Hexagons; 3. Triangles. There is no software (that
I know of) that attempts to expand John Conway's idea
beyond squares. Golly could be the first.
