Check out this cool animated .gif file, one that Markus compiled and decided to present us with! It’s shows a well known relative sizes effect, which is characterized by visually perceived images that differ from objective reality. It results with our eyes seeing one thing, while our brain sees something entirely different. The information that our eyes feed back to the brain has to be understood by the brain, and the brain is very clever at guessing what it should be seeing. Sometimes this difference can be quite astounding! The brick pattern further strengthens the 3d perspective, thus fooling (or helping?!) our brain in what it makes of the image. Cool, ayeh?! BTW, thanks for helping me out on Wednesday ;)
