Javascript Cellular Automata

[yticmic]

I have been working on a javascript cellular automata here:

You can mod the rules while it is running (up to 2B rules and 2S rules now, might add more soon) which is pretty fun. Each cell also has an age parameter, which can be visualized by the fading options (darken either old or young cells).

I have a few preset patterns, and also you can just load a random matrix via the dropdown.

I would love any feedback, it is not yet perfected, but it works pretty well.
