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.)
