Enigma - My favorite. It does whatever my medication tells it to do!
Snake Illusion ad lib - This one will mess with your head.
Stereokinetic Phenomenon This is one of my favorites.
Wagon-wheel effect - Another to make the room spin.
80 Optical Illusions & Visual Phenomena - So many to click on. So little time.

Optical Illusions & Visual Phenomena
Visual Illusion · Optische Täuschung
by Michael Bach
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.
You may be glad to know: There are no tasteless surprises here; you know, these infantile pranks where you scrutinize a picture and suddenly an ugly face (or the opposite end) screams at you…
Don’t distress yourself if you don’t see the effect described, even if trying carefully. For many illusions, there is a small percentage of people with perfectly normal vision who just don’t see it, for reasons currently unknown.
