Somehow, this actually works. If you put in a variation of the old Konami Code on a Facebook page, lens flare effects will appear on your screen. You need to push up, up, down, down, left, right, left, right, b, a, enter key, then right click. Then press up then down. The only way to stop it is to log off or reload the page.
Just thought this was kinda cool. I dunno how many of you have a facebook page, but this is cool enough to try. Not because irritating circles blocking your view is cool, but because it's the Konami Code in mainstream culture.
