Here's yet another optical illusion making the internet rounds. This one states that only "erotic people" will see the circles move. Can you?
Actually, pretty sure everyone can! And that's not because everybody is sexy time.
Sending optical illusions like this via Twitter has been "the thing" in Japan for a while now, usually prefacing them with statements like, if you can see whatever, then you are blah blah. The above image first hit last year and is still popping up online.
