Here’s another film inspired by the video game Portal 2, in which a sort of gun is able to shoot holes in walls, ceilings, and floors, and the last two of them are connected, so if you pass through one, you emerge from the other. Among other things it shows what’s possible even with home computers and consumer video cameras.
