Visual XOR against random data using the supplied "information pixels" instead of actual pixels (2x2 pixel groups). Cryptography at its most simple and most effective, with a visual twist.
Makes me want to fiddle, and make something which lets you hide information in the interference between 3 such images... one message for each pair, and one for all three stacked.
