Someone made a little scene from Portal with LEGO blocks. As you can see it's pretty basic. Maybe a falling scene in an MC Escher style would have been cooler. It doesn't matter though, the main reason I'm posting this is because it reminds me of the portal I opened in my bedroom. Sure I used explosives and a sledge hammer, but a hole is a hole. Now I don't have to walk down to hallway to pee in the middle of the night. I just use the portal to the backyard. It's a little drafty this time of year, but that's the price you pay for convenience.
