“Someone points out something and suddenly a secondary interpretation of an image appears. There’s something a little scary about this process, even when the images are harmless. We have a flash of insight and a new pattern is revealed hiding within the world we thought we knew. It surprises us.” The Atlantic’s Alexis Madrigal on the things you cannot unsee (and what that says about your brain).

+ Did you happen to see the face of Jesus on a piece of toast? Don’t worry, that’s perfectly normal. (I tend to see Moses, but maybe that’s because I usually eat rye.)
