In the video game Portal, players had access to a gun which could literally punch holes in space.
So if Portal was real, what would people use it for?
Film maker Jason Craft used CGI to create his amazingly well-crafted vision of what would happen if a Portal gun was let loose in a regular home.
"I tried to match the game as close as possible," Craft says of his clip.
"This was the most challenging project I have ever undertaken, consisting of 3D tracking, seamless camera cuts and 3D camera projection."
"This started out as an experiment since I didn't think I could even pull it off," he said.
"If I knew it would've turned out as good as it did I would've put more of a story behind it."
