Optical Illusions

A few very fun optical Illusions:








And my favorite for last, the beads aren't moving btw, but your brain interprets them like that because it likes following strait lines and angles.


Another fun one, but you have to follow the rules to make this one work, if it does the pink things dissapear.

So yea, to see it, Look at the + in the middle for a while and don't move .
