optical illusions, ...for those boring days. Options

[xosteffanator]

Okay I am bored so I googled optical illusions and found a bunch
Number 1
For this optical illusion to work, stare at the center crosshairs and move your head in and out from the screen. Sometimes when you just look to the side or relax your eyes a bit, you'll notice the spiral moving.

Number two
Look at this closely. Could it be-the spiral is moving?

Number 3
Simply stare at the white circles and notice the intermittent blinking effect.

Number 4
Try staring at this for more than 5 seconds without going crazy. Then try following it round! Curves constantly die out and then re-evolve as part of another curve.

Number 5
There's certainly something very ambiguous about which way this is meant to be up... I still can't figure this one out.

Number 6
This is the Bunny/Duck illusion. At first glance, what do you see? Now give it some time, but do not focus on one certain area, and then ask yourself; what do I really see? Now, take a closer look. This is an old one.

Number 7
When you first look at this, do you see and old man with ivy leaves around him, or do you see a couple kissing?I still can't see the couple kissing....




Add your own opptical illusions for those boring days. And give me some feedback on them!
