Optical illusion illusions.

Your mind subconsciously interprets this line drawing of an impossible cube as a three-dimensional object, even though it is not actually possible for such an object to exist. [more inside]

The Richard Balzer Collection

"I have been collecting for more than thirty years, and my collecting wanders around the theme of visual entertainment, and almost all of the collection dates from before 1900. Over time you will find magic lanterns, peepshows, shadows, transparencies, thaumatropes, phenakistascopes and a variety of other optical toys. You may find things that seem odd in this collection, however, always remember that collecting is a very personal thing and these items may stretch the boundaries of visual entertainment but nevertheless have found a place in my collection."

The science behind spook hills

""Anti-Gravity Hills" (also known as "Gravity Hills", "Spook Hills", or "Magnetic Hills") are natural places where cars put into neutral are seen to move uphill on a slightly sloping road, apparently defying the law of gravity. Typically, the "spooky" stretch of road is rather short (50-90 m), only a few meters wide, and surrounded by a natural hill landscape, without nearby buildings. Such places are found in several countries all around the world, and have been tourist attractions for decades. They should not be confused with the "Mystery Spots" [previously] found in amusement parks. These are generally tilted cabins, purposely built as such; a person walking inside feels disoriented, getting a very strong impression of standing at an angle in a perfectly normal room." CSICOP and Discovery News explain the phenomenon, and here's the paper on which the CSICOP article was based (PDF).

Here's looking at you/me, kid

More good stuff for people who like visual ("optical") illusions (previously): A nice Scientific American article, a particularly creepy illusion, and a link to the "Best visual illusion of the year" contest. Given that the eye/mind/brain is so easy to trick, a person might wonder what's really out there in the world.

M.C. Escher + Lego = ? I used to make spaceships and houses with my Lego not 3D representations of famous optical illusions! [via Filepile]

A professor of vision science at MIT understands that life isn't just black and white, even though we often see it that way. This amazing illusion proves it, and these slick, fast-loading, Flash demonstrations of lightness perception show how it's done. (My favorite is the "Koffka Ring".) White paper here, for deeper background.

I'm usually not a big fan of optical illusions (unless there's a nice magic trick built around it), but this one is pretty brain-burning. (Yes, that's my entire front-page post. But hey: at least it ain't a news story.)
