My co-worker, good friend and self proclaimed geek sent me this link (forwarded from her equally geeky husband) from Instructables.com. On the site they also have instructions on recreating the famed Blackforest cake from Portal as seen here:
I’ve heard rumor that someone made a cake of the beloved Weighted Companion Cube.
I’d also like to add that today is the last day to get Valve’s Orange Box for PC from Best Buy for only $30.
Even if you have Half-Life 2 and Episode 1, its worth it for the 3 other games. I picked up mine yesterday.
