About This Design
Optical Illusion Key Ring
Instructions: 1) focus gaze on red dot 2) wait for disc to hover and wiggle over the background design 3) be amazed! (it helps if you clicky on the magnifying glass button there to view the product full-size). We're guessing the effect results from the differing characteristic spatial frequencies of the foreground and background that generate error signals during micro-saccades that the brain cannot cancel simultaneously. Science!

Metal Circle Keychain, 2"
Very poor quality. Almost unreadable to the naked eye, imafes on store are much clearer, very misleading.
