Illusion 1: These squares are actually the same exact color. Hold your finger over the boundary between the two shapes and see them change.

Illusion 2: These dots seem to change color and orbit the center. But focus your eyes on a single dot - there's no rotating or color change at all.

Illusion 3: Try to stare at the cross in the center and watch the blank spot, it will somehow turn green!

Illusion 4: Stare at the dot in the middle and move your head in an out towards the screen! The circles will mysteriously move! Spooky!

Illusion 5: Can you see which of the orange circles is the biggest?

...Surprisingly they are both exactly the same size!

Illusion 13: Two Faces! - is this face front on or from the side? It's hard to work out which way is right!

Illusion 14: Which way is the train moving? Try blinking and it will change direction!

Illusion 18: This artists creates clever drawing that actually look like 3D objects!

Illusion 19: Stare at the blinking green dot and see what happens to the yellow dots!
