I know this is slightly off-topic to this forum, but I saw someone wearing a cool Portal shirt today, but cannot find it anywhere. If anyone knows where I can find it, I will love you forever. It was black, all the icons were in grey. It had the top part of this: http://www.redbubble.com/people/dtdream ... style=mens and the cake picture below. It said 'Piece of cake' on it. Appreciate any help, thanks!

Might've been a custom t-shirt made at a print shop.
