Field notes
Each canvas may add constraints: black squares are left empty, while a rectangle marked with a small corner square is fixed. Players can revise a painting, change rectangle colors, and sign it for the wall. The page also offers statistics and an archive; cross-device syncing uses a shareable code, which the site cautions gives anyone holding it access to the linked record.
