To promote his book Dot Robot: Atomic Swarm, children's author Jason Bradbury built a replica of one of the characters, Punk. The only trouble is that—with some CGI help—the spiky, spherical robot turned against his creator.

Jason, the guy with the destroyed kitchen, was actually the fellow who showed us how to build a hoverboard in the past. Oh, if only he had one on hand to chase down that robot. [Jason Bradbury]
