This WebGL app spins "crop circle" and other patterns at varying rates of rotation to reveal hyper-dimensional images.
At certain spin rates you may notice harmonic images appearing that don't appear on the pattern when paused.
Many of the circles are based on real crop circles that have appeared in crop fields around the world.

Browser compatibility: Should work with recent versions of all browsers.
Internet Explorer may require the installation of the IEWebGL component.
Safari on Mac, if required enable WebGL.

Ye be worthy and watch for the mantis and reptiles.
They are amongst you
Some are your friends
