I love getting those optical illusion emails. You know, those graphics that you have to stare at for a long, long, long time and you have to see the hidden stuff, or find something that doesn’t seem to be there but is there? :D
Here’s some sort of an optical illusion, from Gadgenista. Like what she said, this is too good to pass up. :)
Is the dancer spinning clockwise or counter-clockwise? More details about the illusion under the cut. :)
