I have made a cellular automaton program on Khan Academy. It uses JavaScript, and can run all life-like cellular automata, as well as all non-generations members of MCell's Weighted Life family (but you have to change the code to get the weighted rules).

I use vectors. That way, the pattern can grow unbounded and any neighborhood can be specified, but the code has to be changed to specify a rule (especially non-totalistic(especially non-isotropic)), and the time needed is approximately proportional to the cube of the population. Despite this, it seems to be the first one of its kind:
