Optical Illusions

Check out '86 Optical Illusions & Visual Phenomena' at http://www.michaelbach.de/ot/.  This is a fun website with lots of things to do and play with.  According to Michael Bach himself at the top of the page:

These pages demonstrate visual phenomena, and »optical« or »visual illusions«. The latter is more appropriate, because most effects have their basis in the visual pathway, not in the optics of the eye. When I find the time I will expand the explanations, to the degree that these phenomena are really understood; any nice and thoughtful comment welcome.

Here's a list of the categories the phenomena are separated into:

• Motion & Time

• Luminance & Contrast

• Colour

• Geometric- & Angle Illusions

• Space, 3D & Size Constancy

• Cognitive- / Gestalt Effects

• Specialties with faces

According to thier website:

This site is designed for fun. We get a kick out of making "chimeric faces", or, " face flips" as we call them, and have automated the process so we don't have to use  Adobe® Photoshop® to do the image manipulations every time.
