Thanks to Bob Levine and his friend Leon, we now know about a funky new Facebook Easter egg–magic circles!
While on Facebook, perform the following actions to activate the Easter egg.
Press UP, UP, DOWN, DOWN, LEFT, RIGHT, LEFT, RIGHT, B, A, ENTER key, right-click on the Facebook page (if a context sensitive menu appears, click away from it to hide the menu), and then press UP and DOWN.
Voila! Magic circles will appear!
If you don’t see the magic circles right away, try typing something into your status box. If they still don’t appear, refresh the page and start the sequence over.
The only way to turn off the magic circles is to log off or refresh the page.
