I saw a whole bunch of rad Portal costumes this weekend! So starting at the top left, that's a human Wheatley and GlaDOS, who were incredible. Their costumes lit up and stuff! And then Space, Fact, and Adventure cores, which were awesome, haha. Then a Portal group with a 1950s test subject, Cave Johnson, and Chell (with companion cube). You can't really tell from this picture, but they had a potato with them too, haha. Then lastly, THE MAN WHO'S GONNA BURN YOUR HOUSE DOWN. WITH THE LEMONS.
