I have an 8x8 cube that takes me about 15 to 20 minutes to solve. Oddly enough (pun intended) since it’s an odd number there are a few things that makes a 17x17 technically easier to solve. With even numbered cubes you can get into a few situations that require extra steps. The same steps can be used to solve a 17x17 that are used to solve a 5x5 cube actually. It just takes a LOT longer and a LOT more hand cramps. I’d love to do this once just to say that I’ve done it.

The shuffle was videoed, just watch it backwards FTW!

Would this count as proof-of-work?

Why do they bother calling it a 17x17x17 cube? Why not just a 17 cube? I suppose there are 2x3x3 rectangulars, but are there bigger ones? Is there a 17x23x37 rectangular cuboid out there? A 17x17x17x17 hypercube?

A Rubik’s tesseract! Only the Princes of Amber can manipulate it.

The colors change over time

And only then if they walk towards someplace in Shadow where it’s already solved.

Technically, it doesn’t appear to be a cube, what with the convex faces. And while it may not have definitional relevance re: “cube,” it also has uneven-sized pieces.

But I’m at the edge of my geometry knowledge here…

Good on him but I don’t think this is anywhere close to “fast.” There are a few of people that can do 11x11x11 in <18 minutes. Fast for this should be under 30 minutes.

The only reason we don’t see those times with this 17x17x17 is that the cube costs like $700

Maybe we already are watching it backwards…

I feel like I just watched Rocky VII. That is, I am none the better for having viewed the last four incarnations of this progression.
