Figure This!

The image that forms on your retina is flat, yet you see a world of shape, color, depth, and motion.

Nature uses camouflage illusions that allows both animals and insects to match their surroundings so they are undetectable.

The Poggendorf illusion, discovered in 1860, is one of the most famous distortion illusions known and uses colored lines passing through a rectangle.

Mirage comes from the French word mirer, to look at; or se mirer, to be reflected. A mirage may include the appearance of lakes in deserts or on hot asphalt roads, the images of ships and icebergs (frequently seen as if inverted and suspended in the atmosphere of the Polar Regions), or “looming” as witnessed in mists or fogs.
