Log into your Facebook page, then press the following Arrow Keys on your keyboard for the lens flare effect:
Up, Up, Down, Down, Left, Right, Left, Right, then B, A and Enter key (not return key).
Red lens flare circles will now appear. The only way to get rid of them is to log off or to refresh the page.
This key sequence is also known as the Konami Code, and is a cheat code/easter egg code in many websites and games. timothymh - Jan 12 2011 6:40PM
