If the image isn't moving, you're in good shape for driving etc.

The more the image moves (the central column rotating leftward, anything else rotating rightward), the more exhausted you are.




This isn't a gif, by the way. It's a single jpg.

If I look at the central column, it moves very little, but if I look to the left, it moves quite a bit.

[bob48]

When I look at it without moving my eyes it stands still but when I move my gaze it moves slightly. Where did you find the image? I'd be interested in reading whatever article went with it.

[bob48]

It means that you should stop eating those wild mushrooms you found growing on your lawn.

[Gusington]

Or eat more.

[DoctorQuest]

What does it mean if I can't see it at all?

[Sir Slash]

Put your glasses on. Or somebody else's on if that doesn't work.

Or the link's busted. ;)

One of my friends posted the jpg on Facebook a few days ago, and we've been having some fun with it. It was generated by a Ukranian graphic artist named Yurii Perepadia, aka "Guten Tag Vector". Here's a link to his optical illusions on Shutterfly:
