If watching the rapid flip of the colors doesn't make you queasy, take a gander at this astounding timelapse video, which shows Kenneth Brandon tackling a 17x17x17 Rubik's Cube-type puzzle. He speeds the whole thing up, so that the puzzle goes from scrambled to solved in just six minutes.
The Over the Top cube was designed by Oskar van Deventer and there are only a handful of these expensive, 3D-printed puzzle monstrosities in existence. Brandon borrowed this particular cube from his friend Aaron MacDonald, who has already solved it.
The cube has 66.9 quinquagintatrecentillion possible positions, and you can see the sped-up version of Brandon moving the pieces into place below:
And if you have 7.5 hours to spare (or just want to see how one goes about solving such a large cube), you can watch the entire solve in real time:
