video: sparsematrix 3D

sparsematrix with 3D graphics based on outer totalistic cellular automata rules with history. the rules are defined very similar to game of life by specifying how many of the 26 neighbouring cells (i.e. moore neighbourhood in 3D) have to be "alive" for "birth" and "survival" of the centre cell, together with the decay parameter which defines how long a cell is dormant after "death".
