checker shadow illusion

I found this site via del.icio.us today, and couldn’t believe what it showed until I experimented by placing a sheet of paper with two holes cut out over the screen.

I’m reproducing a tiny version of the image to lure you to the large version…

See the Illusion…

I grew up in New England, moved to the Carolinas in '98 to start working at what was then a large regional bank and is now a really big nationwide bank. I work doing intranet content management and intranet site management. After work, I practice Aikido, knit, ride my motorcycle, read, watch movies & eat. I've been studying Aikido since 2014, and I ride an old Honda Shadow. Someday I want to go skydiving, and I am pretty sure that I want to hike the Appalachian Trail someday.
