Welcome to Follow-Up Friday!

By this time, you know the drill. Follow-Up Friday is a chance for us to revisit the subjects of previous posts and bring the PuzzleNation audience up to speed on all things puzzly.

And I’d like to return to the subject of twisty puzzles.

Last week I wrote a post discussing how 3-D printing is changing the way Rubik’s-style puzzles, or twisty puzzles, are being constructed.

One of the puzzles I mentioned was a monstrous 17x17x17 cube known as the “Over the Top” Rubik’s Cube, created by 3-D puzzler Oskar van Deventer. It’s the world’s largest Rubik’s-style puzzle, and a visually staggering artifact.

Well, as it turns out, not long after that post went live on the blog, I discovered a video of a twisty puzzle enthusiast SOLVING the 17x17x17 Over the Top puzzle:

Solved in seven and a half hours over the course of five days, this puzzle whiz (who goes by the YouTube handle “RedKB”) documented the entire process, then did a time lapse to compress the video into six minutes, as you can see in the clip above.

(For the fascinated, he’s also uploaded the entire seven hours of solving so you can see the complexity of the cube in its full, mind-boggling glory.)

It’s one thing to discuss these puzzles, and quite another to watch someone accept the challenge and then conquer it. A truly impressive puzzly effort.
