Here’s another ambiguous severed head illusion. Is Koala thoughtfully holding up the severed head of Woven Person for inspection, or is it the other way round? You can see it both ways. For examples of this illusion in earlier posts, check out The Screams after Munch, the Monks, and the Mask/Skull illusion. (On that link this illusion may be at the top of the page, if so scroll down for the previous versions).
