This tool lets you generate custom Doom levels with your Roomba

The best use for a Roomba this holiday season isn’t mopping up after a spirited Christmas Eve — if you’re a gamer, that is. This week, industry veteran Rich Whitehouse published a tool that can generate levels in id Software’s iconic first-person shooter, Doom, from real-life interiors mapped by iRobot’s autonomous vacuum. He christened it “Doomba,” a punny portmanteau of Doom and Roomba.

“I … realized that there was a clear opportunity to serve the Dark Lord by conceiving a plethora of unholy algorithms in service to one of the finest works ever created in his name,” Whitehouse wrote in a blog post.
