Facebook developers seem to love Nintendo and Contra.

How to Enable Contra Mode on Facebook:
– Go to Facebook and sign-in to your account
– Make sure you cursor is not in any text fields or status field
– Enter the Contra code (up,up,down,down,left,right,left,right,B,A) then hit ENTER

You are now in Contra mode. Scroll up and down and you get neat little bubbles around facebook. Pretty useless and has nothing to do with Contra, but still cool!

I wonder what other neat tricks Facebook developers have hidden?
