The rules could be parameterized by a four-digit number two digits bounding the neighbor count for birth and two digits bounding the count for death. I took an evening an encoded a nifty 3-D display on the Ardent in Dore (similar to PHIGS). I allow arbitrary rules. I didn't write an interactive graphics based method of specifying the initial state, That would be useful. Also the Dore implementation was not fast. I just applied a translation matrix to a cube. Using lots of transformation matrices is inefficient in Dore.
