First there is 12 then when it moves there is 13? I think it is great I don't know how it works :(

OMG so confusing?

[louder]

Lol, thats just confusing.

I noticed when it changes back, it doesnt go back to the same place it was when it switched. Theyre probably playing a dumb trick

[FlyingJesus]

No it is something that really works, I had a paper version of it in an optical illusion book when I was little :P

[Splinky]

Eh? thats weird. Try the mind reader test on there. The first one is SCARY

The chap on the bottom left only loses part of his head, hense why it goes from 12 to 13. Watch it a few times and keep your eye on him.
