They said it couldn’t be done, but Oskar van Deventer—a longtime puzzle maker living in the Netherlands—created it anyhow: a 17-by-17-by-17 tile Rubik’s cube that, as far as we know, is an unofficial world record for the world’s largest and most complex Rubik’s puzzle.
Van Deventer, an electrical engineer by trade, didn’t carve out the 1,539 constituent pieces by hand, but rather tapped the increasing availability of 3-D printing technology to manufacture his high-tech puzzle. That’s not to say it was easy; the design itself took more than 60 hours (and three tries) before a successful prototype was printed at Shapeways, an online commercial provider of rapid prototyping technologies. Dyeing the individual pieces required another 10 hours.
The finished product, titled “Over the Top,” is 5.5 inches and 17 tiles long along each side when assembled, blowing the current record of 12-by-12-by-12 out of the water (though, as noted above, this world record is currently unofficial). Want to give it a shot? You can print one out yourself at Shapeways for a cool $2,000. Judging from the looks of it, that comes out to about $1 per hour you’ll spend trying to solve it.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

Sadly the puzzle is only 15x15x15, you can't count the black tiles as pieces of the puzzle as they will always be black and therefore will never need to be "solved" for.
What does it matter if they don't need to be solved? They are still pieces of the puzzle. And 17-17-17 is still the 'size' of the puzzle.
Obviously, you are not a golfer.
And I get lost in a 3x3x3 rubix cube
Rubik's cube only in name. Cubical shape for 7x7x7 or more with equal layer width will not allow for turning of outer layer in two adjacent faces, because the corner piece will then be completely disconnected from the rest of the cube (see elementary geometry). Barring magnets/gravitons, that's a dud in my books.
bad news:
"The puzzle will be first presented live to the world at the New York Puzzle Party Symposium, Saturday Feb. 12th (by invitation only!). A YouTube video will be published after that event."
Am I the only one who counted 17 non-black tiles in a row on the picture?
