Number 1:
This is by Julian Beever, this is probably his best.
You can see his entire gallery here.
Number 2:
It rotates, it doesn't rotate, who knows. Just have to stare at the center black dot, and move your head forward and back.
Number 3:
The gears move when you aren't looking at them. Or do they?
Number 4:
Move your head forwards and backwards. Even looking at it is confusing.
Number 5:
This one is possibly the most confusing. The blue and the green are the same color. Open it in paint and use the eye dropper if you want proof.
Number 6:
A classic illusion, the white dots turn to black when in your peripheral vision. Confusing, no?
Number 7:
If you stare at the green dot in the middle for long enough, the yellow dots will disappear.
Number 8:
The movement created is really strange. For more fun, scroll by this, and watch the green shapes move.
Number 9:
More of a perception confusion than an actual illusion, but still. The real question is, which way is up?
And... Number 10
Well, I'll just give you a link. Go see this one for yourself Here.
