Saw this at Kotaku. Somewhat clever, but a real WTF moment for anyone who hasn't played the game.

I agree with the Kotaku writer: Merely mentioning cake in the context of Portal should no longer qualify as a joke, if it ever did. You really have to do something with the premise, else it's hella lame.

Ha nice. Reading in the comments, it appears the phone number goes to valve support. So much for my bright future

Nice. I keep meaning to put something portal themed up in our common room. I may make a life sized portal with an enlarged photgraph of somewhere else. I don't have a printer big enough though, even school's A3 one isnt big enough

Hahaha thats pretty cool, i should make one of those for the heck of it, maybe collect some of the valve stuff with it.
