From my buddy Mark:
“Go to any Facebook page and click once in a white area just to get a blank timeline to do this with. Press up arrow, up arrow, down arrow, down arrow, left arrow, right arrow, left arrow, right arrow, B, A, then the Return key. If you left-click or right-click, scroll or push any keyboard key after that, a strange shining set of circular rings will appear on your screen.”
It’s the Konami code: http://konamicodesites.com/
