wow- amazing work! reminds me of the cheese block. I love the look of the core, the pentagonal centers on a cubic core looks so wrong yet oh so right at the same time.

First off I need to say AMAZING JOB!!! :mrgreen:

This is a puzzle that will stand the test of time.

With that said I have conflicting thoughts about these types of puzzles. Solving would be great and fun yet what about scrambling. A good puzzle should take just a couple random twists without looking to make it a jumbled mess. This however looks like it would be "tough" to scramble because of having to align four centers to make a rotation. When solving this isn't a problem because it is just part of the puzzle adding to the challenge. What are your thoughts?

Coolest idea ever. Have you thought about making the reverse (Circle Megaminx with normal circle-cube circles)?

This must be mass-produced by somebody, because it's original and awesome!

Seriously, this is amazing.

At first I thought that the circles somehow turned based on the face that it's on. I'm kinda disappointed that it's babyfaced.

you're right! with this puzzle is difficult to play ... I'm sorry, but I could not think of how to bandaged the circles and faces ...
but I could not wait and do it in style BabyFace. If someone proposed an elegant idea - I'm ready to remodel this puzzle!

I'm afraid it may be too easy to knock off. Amazing puzzle and all but if it gets mass produced I'm not sure if Grigr will be on the producing end.

Great work. I am in awe of it's simplicity as a concept and it's excellence as a puzzle. Please, do the puzzle justice and put it on Shapeways

The bandaging would be an issue I think, not only because of the conflicting angles but also because 4 stars have to be lined up so a layer can rotate. I shall have a think but it seems impossible to me.

Like if it would not be there would probably have a problem with the circle/star alignment.

I love simple ideas like that! *Standing ovation*
Now only if I had the money to afford such things o_o
Although, I must admit it'll be annoying to have to adjust the pentagonal face like that everytime

Bravo. Really cool new concept.

It looks like, with patience, it can be very satisfactorily scrambled.

I thought it might be neat and more convenient if an 8 prong star version were made. I made a quick sketch and I think it might look something like this.

very interesting! you can do it;)

I have neither the experience nor the money to create and print such a puzzle. But anyone else is free to take a crack at it.

Oh I like this idea. Unlike the 5 pointed star version you could tie the circle moves to the core in some interesting ways. Imagine a puzzle which looked like this where each 90 degree face turn resulted in the circle on that face turning by 45 degrees.

So something like this?

Thats a nice idea, but I can't see hoe that would be possible without the use of gears. That would probably make the puzzle aither really large (and expensive) or not turn very well.

just my 2 cents

Sharkretriver · **Joined:** Mon May 24, 2010 2:30 pm

What would solving the 8-pronged gear one be like, one that only allows 180 turns, but then with another step in the solution?

90 degree turns would be allowed too.

Yes, I too believe this would need gears. So this is probably a potential Oskar puzzle. I don't think anyone else is touching gears yet. As for how well it will turn... I have no idea. But I do think it would be a very interesting puzzle. This may be a great candidate for a Gelatinbrain puzzle.

Watch Oskar do this in 5 minutes. Guarantee it.

I might take a crack at making that 8-line version myself, if you don't mind...

I'd love to see an idea of mine come to life.

polymaker · **Posted:** Wed Aug 31, 2011 12:25 pm

I made a pretty straightforward mod, just a six-pointed star:

I really like the concept "align a cut to allow turning" from your puzzle, wich can be ported to almost any puzzle shape.

I tried it on a reuleaux tetrahedron and I like the result :

shzl · **Joined:** Mon Oct 25, 2010 2:13 pm **Location:** London

maybe you should make that last one with a crazy tetrahedron, and shapeways centre pieces (within the circle) would that be possible?

Plus this whole conversation has gotten pretty off-topic.. Allow me to correct it :lol:

Grigorusha, why are the edge pieces of the inner megaminx (within the circle) slightly raised compared to the rest of each face? Is this to help the turning of the baby-faces?

Would it be possibler to have those 5 pieces per face flush, and instead have the centres raised a bit?

And do you have any intentions of selling this on shapeways?

And lastly, I had an idea that may make it easier and quicker to turn 4 babyfaces to align. How hard would it be to have more tolerences (to make it looser) but instead have a slight *click* when the cuts line up to allow a move? Possible a click similar to turning an outer face of the V cube 6?

Did you use more Crazy Cube techniques than Crazy Megaminx techniques, or vice versa?

it BabyFace puzzle, it can not be solved as Crazy puzzle

Ah, right! It's more like a cross cube than a crazy puzzle, since it's babyfaced.
