Don’t expect to run into Doc Brown with this Time Machine: It won’t let you travel through time, but it sure can make time go by faster (…or slower, depending on how you look at it). The Can You Imagine Time Machine Kinetic Display Clock is a Rube Goldberg contraption that keeps time by rolling around a bunch of chrome balls.

It might seem complicated to read at first, but don’t worry, you’ll get the hang of it. And if not, it’s still a fun accessory for your dorm room, home or office! This three-tier time keeper transfers a chrome ball every 60 seconds for a constantly moving display. It comes in a transparent acrylic case for a polished presentation.
