Click cells to flip ↔. Find the original board
that, run forward, produces what you see now. ▲ orange = where the ant ended.

Langton's Ant rules
Each step, the ant looks at its current cell:
White → turn right ↻, flip to black, move forward.
Black → turn left ↺, flip to white, move forward.
Important: when the ant arrives at its final cell,
it has NOT yet flipped or turned on that cell — those actions belong
to the next step. The arrow shows where the ant is sitting and which
way it's facing. The cell BEHIND the arrow is the one that just
flipped. Ant stays within the board.
