If you keep your eyes really still, they stop moving
Awesome picture though!
The last time I keep my eyes really still fixed on something, she slapped me.
I just thought of something diabolical.
Have the image in the OP (or some other that's similar or worse) made into a poster. Plaster the poster at some public setting (bus stop comes to mind). The instructions above the image would read something like:
Stare at the image below for no less than 1 minute. Then turn around and look at X (X could be anything that's nearby, i.e. the brick facade of some building). A secret image will be revealed to you that no others are capable of seeing unless they, too, follow these simple instructions. If at first you don't see the secret image, repeat the process, perhaps staring longer than 1 minute, for some peoples' perception is keener than others. Only 1,000 winners will share the Grand Prize. Good luck! (somedomain).com with QR-Code for good measure, directs to a purposely-created 404-401 Error Page depicting more vague language.
