Canvas 12 was a 24-hour canvas, the smallest so far at 80x80 pixels. It was the first canvas to be filled 100%. Toward the end of Canvas 11, two polls were held for a future canvas: its shape (won by 'rectangular', with 'square' getting decidedly fewer votes) and whether or not to bring back the old purple color (won by 'yes'). It was only after the launch of Canvas 12 that it was revealed that the canvas would only last 24 hours, and that the shape vote would apply to the next canvas (Canvas 13).
