Cayetano Ferrer is a Chicago based artist whose work involves (among other styles) painting street signs with the images of the items immediately behind them, to give the illusion of transparency (depending on what angle you're viewing from). The latest campaign by Amnesty International seems inspired by his work.

Spanish Castle Magic. Stare at the dot in the center of the image for 30 seconds, then mouseover the picture. Don't shift your glance, because until you do the picture will appear to be in color, despite the fact that it's in black & white.

Turn Your Head is an online service that echoes the famous "two faces/chalice" optical illusion, but in the real world. You provide them with shots of your profile, and they carve a wooden sculpture of the image for only $149.95. Works best for those with uniquely pronounced features, not to mention those with $149.95 to waste on useless crap.
