Cool Optical Illusion Collection #4

My favorite illusion video
Well, you asked. It's the link above.

Spinning Spiral
This spinning spiral will appear to move, even though it is does not!

Incredible spiral arraws
This is one of the new illusions added to the site. Makes a nice wallpaper for your computer too!

Have some fun! Try the Ambigrams Section.
An ambigram is defined as a word that is the same upside down. Very fun, and make great tattoos too!

Missing Piece Illusion 2

13 times 13 = 169 squares

8 times 20 = 160 squares

Here is another grid type puzzle. The shapes are identical in the two images above, but the second image actually has 9 less squares than the top one! Where did all those extra spaces go?

HINT: There is a similar puzzle on the site that explains what is happening in this type of optical illusion. But I feel that the effect is so strong, you may just want to believe it's magic. Remember, you'll have more fun not knowing how it's done! Just enjoy it!
