The instructions are: “THE FACEBOOK TRICK: press up,up, down, down, left, right, left, right, B, A, Enter key, then right click then press up and down and magic circles will appear when you make a mouse click. the only way to get rid of them are to log off or refresh the page…IT WILL WORK! put this as your status if it works.”

It does work. I didn’t get it to work immediately because it gets a bit blurry after the right mouse click, but it works. I tried it in Firefox on a MBP.

One of my Facebook friends found the explanation in the Konami Code.
