Optical Illusions Art Collection #2

Spooky.	Scary.

Ambiguous Cube

Stare at this cube for awhile. The blue side of the cube will appear to be either on the inside or outside of the cube. It's either the closest side of the cube or the farthest away. It's tough for our minds to perceive this optical illusion both ways, so you'll see it switch back and forth the more you stare at it.

Another thing we've found with this blue and yellow cube is that it's not just this: At first, the blue wall appears to be on the back side of the cube, with the yellow sides on the right and bottom, coming out toward you from the blue. Then, as it switches in our minds, the blue side is closest to you, with the yellow sides now on the outside and also very close to you, but they're pointing away.

Like we said, the more you stare at this illusion, the more you tend to appreciate it because it will just keep doing that! Cubes that do this are called a "Necker Cube" and you'll find them throughout the site. It's perhaps the easiest optical illusion to draw as well, so try it out, next time you're taking notes... jot one down, and shade in a couple areas of the cube, and who knows what you'll come up with!

	Same Shade Diamonds Our newest optical illusion. We just created it on 10/10/2009 Wow! It will look like the diamonds on the top are much darker than the diamonds on the bottom. You won't believe how amazing this incredible optical illusion is.
	Moving Backgrounds Created 9/24/2009 It moves! You must zoom in to get the full illusion. You'll see the rings rotate, even though they are not moving at all. We've created several sizes so you can use as your desktop background.
	Scary Faces Illusion Created 9/17/2009 Watch as the scary faces disappear before your eyes. The longer you stare the stronger the illusion. Perfect to send to your friends for Halloween!
	The Obama Illusion We made this original Barack Obama Illusion and then we made it famous! Stare for about 30 seconds and you'll see his ghostly image appear on the wall!

	Moving Spiral Illusion A version of our original moving spiral illusion was recently published in a popular college textbook. It uses multiple illusory principles to give the illusion that it is moving when it is absolutely not moving. Big enough to be your desktop background!
