We are all familiar with the duck-rabbit illusion – an ambiguous image that looks either like a duck facing one way or a rabbit facing another. Or the Necker Cube. Such illusions have one thing in common – they flip back and forth between two equivalent interpretations.
The two designs below flip and flop between flip and flop! The first can be read either as “Flip” or “Flop” – but we can hold on to just one reading at at time. The other employs a visual pun on the letter “i” or an image for “eye” (or becomes “o” when flipped by 90 degrees).
