Put a square on the board. It gets printed.
One shared board, 250 × 250 squares, sixteen colours. Anyone can paint — no account, no allowance, no cooldown. You can paint over anyone; anyone can paint over you. On the 1st of the month the board locks, and whatever is on it at that moment gets printed exactly as it stands, then goes on the shelf downstairs.
Nobody decides what it becomes. That is the whole feature.
