About This Design
Optical Illusion Keychain
Instructions: 1) focus gaze on red dot 2) wait for disk 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!

Beyond expectations. Choice of artwork is overwhelming, I found exactly what I needed from SJW_Graphics. Detail, colors, overall design looks great on this keyring. Could use as a pendant, purse charm, bookmark, too! Metal is sturdy without being heavy. Colors beautiful, with clear margins. Customized name makes this gift extra special. So many fonts, so many colors & sizes!
