This could be useful for dead-drop style communications. Should be easier for two people to memorize how to draw a reasonably complex shape than an arbitrary string of bits, numbers, or letters. If you can do that there's no risk of leaking the drop location: just draw it, scan it to check the drop, then destroy the drawing.
