Hex Cellular Automata

I have a project that could use a massive field of fluid as a base. To do this I'm going to need to be able to do a decent speed fluid simulation, This is my first attempt at doing any sort of fluid at all. My previous post shows the various states that the cells can have. I managed to cobble together a decent JavaScript implementation.
This implements a 350x250 hex grid, The actual field size that I want to have will be much larger and will require GPU accelleration.
