Portal was one of 2007′s most popular games, and it’s sequel is one of next year’s most anticipated. Plenty of people probably wish they had the Portal gun in real life, but this mirror trick is the next best thing. It’s fiendishly simple — a Swedish fan simply bought an oval mirror from Ikea and put Blue paint around it. Now, if you put an orange mirror somewhere else in the room and did some mirror trickery, that’d be super impressive. As it stands, this idea is still awesome.
