Because of distortion caused by the grey bars, this still image has a strobing effect that makes it appear as if the water is flowing.

One tiger is easy to see, but there's a hidden tiger too.

If you haven't figured it out, read the tiger's stripes.

This image appears to bulge in the middle, but all of the lines are completely straight and parallel! The apparent warping is caused by the placement of the black and white pips in the corners of the squares. See the next image for an overlay that will make the illusion more obvious.

With straight red lines overlaid on top of the image, it becomes more obvious that the bulge is an illusion. Still, the illusion is so powerful that even the red lines seem to want to warp a bit!

3D artist Qi Xinghua painted this massive sidewalk illusion which earned him a Guinness Book of World Records entry as the largest 3D painting in the world. Presented at a shopping mall in Guangzhou, the illusion is 100 feet long and took over a month to complete.

_____

Created in Paris by Francois Abenalet, this ingenious sidewalk installation goes beyond the usual chalk drawings by incorporating actual grass and trees. It's a classic example of anamorphosis -- a distorted image that only takes its "proper" form when viewed from exactly the right angle.

America's first president gets a little homage in this illusion, which includes both a picture and a signature that work equally well when viewed upside-down.

LEGO mastermind Henry Lim has used the plastic blocks to create a convincing three-dimensional version of M.C. Escher's famous mind-boggling lithograph, "Relativity."

This purple swirl seems to move eerily, but it's actually a static image. As with other illusions of this type, the motion seems greatest in your peripheral vision.
