The 17x17x17 Over the Top cube is a puzzle enthusiast's worst nightmare and their dream come true, all in one. 

With a bit of spare time on his hands, Kenneth Brandon decided to tackle the behemoth, designed by Oskar van Deventer, and uploaded a timelapse of his incredibly impressive effort. 

The task took him around seven and a half hours to complete (you can watch the full length video of that here if you like) but to save you some time, you can watch the shortened version below, where he manages to solve what has been declared the largest Rubij's/Magic Cube in the world by the folks at the Guinness World Records.
