Hi!

This puzzle was suggested to me by Werner Schachinger from Austria. He said that I could name it myself and I called it Rotoskewb. It is a Skewb (a little offset) whose faces have circles that may turn with their 6 segments. If you turn it like a normal Skewb, 3 circles rotate by 5/6 turn and 3 others exchange their segments. Of course, hexagon and 2 other parts of the face area always have the same color, being not connected physically.

The mechanism is obviously based of gears. Interesting, I did not have to design the gear layer - I just copied it from the Gear Pyraminx, because it works the same way that is needed for Rotoskewb. If you have a Gear Pyraminx, you can try to apply shift to 3 edge gears around one corner and you'll see how this puzzle works.
Turning is not that easy and smooth because slow movement applied to the outer layer is converted to faster movement of the gears and this lever law does not work in our favour - bigger force is needed.

:shock: Great work again. It's amazing how much of this puzzle is hollow, I always expect these gear puzzles to be chock full of mechanism.

Oh, so that's what the Hexagon Skewb was!
Really nice, I wonder if this can be applied to other puzzles...

Very interesting idea. Those small circle slivers remind me of the Thorny Cube.

Would a more-offset version be possible? That way the lines in the circle would intersect and cut out some more pieces to make it a little harder.

...Or maybe even a Master Skewb variant, overlaying the cuts with their mirror image? Probably too many tiny pieces for that...

Yes, that was a "temporary" name. :)

I think so. Actually I was thinking about making another version, where the lines on the circle form a David's Star. Probably that would not require much rework from this - just the outermost layer.

Congratulations, this turned out great!

And thank you for mentioning my name! (Hi all, I am Werner!)

In the video it seemed to me that after starting the first corner turn there was a small delay until the circles startet to move, but the same was not the case with the second corner turn. Is there some asymmetry in the mechanism?

Do you have plans to make this puzzle available on Shapeways?

Welcome to the TP forums, Werner!
Interesting idea!
