There's something about repetitive motion that's just hypnotizingly relaxing. This DIY, laser-cut marble machine is a perfect example. Crank the handle and the tiny marbles bounce up their little escalator, swirl down their track and start all over again. I could watch this all day.

If that looks like exactly the kind of distracting toy you could use on your desk, you can buy a kit from Busted Bricks for about $21 (£12.95). Some assembly is required, as is some glue, but when all is said and done you'll have a fun repetitive task to take your mind off of all the non-fun ones you have to do. Or you could just watch this video on loop. That might work just as well. [Viral Viral Videos]
