I was trying to make a tile that would replicate until it filled an area, but I accidentally made a fractal instead!
I can't remember what this fractal is called, but I've definitely seen it before. Thought it was a pretty cool accident, though. It emerged from these rules:
- each tile creates new tiles left, right, up and down
- if two tiles occupy the same spot, both are destroyed
(If I hadn't screwed up, only ONE tile would be destroyed in the second rule, not both.)
