Mastercard has decided to rebrand and are now known as "Mastercard worldwide" with a new logo, shown below. I don't know how many gradients there are in there nor why the middle circle is off-center - but the obvious connection made by Matt at a.wholelottanothing [1] made me laugh until I cried. And they thought they had image problems before.....If you don't know Goatse [2] (safe Wiki link) you will not understand.

Warning: If you do not know Goatse do not google Goatse. You don't want to see it. Trust me.
