Quite A Few Optical Illusions

If you enjoy optical illusions, make sure you check out Michael Bach's Optical Illusions and Visual Phenomena. The site presents 63 of them and explains that visual phenomena is a more accurate term than optical illusions, because the effect relies very little on the optics of the eye and much more on the workings of the visual pathway. Whatever you call them, you can look at them to your heart's content here. He has them divided into categories such as the following: · motion and time · luminance and contrast · colour · geometric and angle illusions · space, 3D, and size constancy · cognitive/gestalt effects · faces Sometimes there are explanations for the effects and sometimes there aren't, but they're all definitely worth a look.
