OPEN SOURCES · CHECKABLE SIZES

Sources & credits

Every playable object has a measurement source, and every drawing has a licence. Measurements are normalized to the axis named in each round.

Drawing credits

Organisms are traced from PhyloPic, coastlines and borders from Natural Earth; landmarks, vehicles, instruments and everyday objects are original project vectors, with familiar interface symbols from Font Awesome Free. All of it is shape only — the colour and the outline are applied by the game, which is what lets three libraries look like one set.
