SandPond is an engine for cells that follow spatial rules.
It's heavily inspired by Dave Ackley's T2 Tile Project.
For more info, check out the SandPond Saga video series.
Atoms follow simple rules, like this one:
@ => _
_ @
The @ represents the atom.
The _ represents an empty space.
So... the rule makes the atom fall down if there's an empty space below it.
