Spill: Splitting and merging

You can split cells into smaller cells.

$: rule().from("A").to("AA")

You can merge cells together.

$: rule().from("AA").to("A")

By the way, when you’re splitting and merging cells, you can sometimes get your world into states that are hard to undo. If you ever get stuck, remember to reset your world.

$: world()

Anyway, yes, you can make fractals with this sort of thing.

$: cell("R").color("red")
$: cell("B").color("blue")
$: world().to("R")

$: rule().from("R").to(`
  RR
  BR
`)

That’s it really.
