Very simple, but looks nice! This is prototype. Inventor is Alexander Solonenko.

This looks right out of the freakin box! I like the thing that its an sphere but still can stand still on the shelf! Really really beautiful puzzle!

I want to call it Caged Ball :P

hehe I am in no position to say anything like that, but really good job!

Alex :wink:

It is somewhat like a Peter's black hole where you can only move the inside pieces of a cube.

Nice! Kabalabda style!!!
I always believed that caged techniques have a lot of potential.

This isnt that impressive to me. All it is, is a 2x2 rubik's ball inside of a simple cage. Just seems to make the turning of the ball harder. I guess it forces you to orient the cube. Still pretty cool though. Looks very very nice.

Very, very clean build. It looks like it would be fun to play around with, but it also makes me wish the actual cage could turn too.

It really would be awesome though if the cage turned too. It would have to have a pretty complex mech to do that though.

What's cool about this puzzle is, I don't think there even needs to be an internal mechanism. It could just as well be a solid ball cut into eights. The outer frame holds the pieces together.
Really cool concept. I love it.

For all of you who say it isn't impressive, how would YOU squeeze that ball into the cage, without breaking the cage?

Make the cage in two parts?

Oh, I was underthe impression that the cage was 1 solid piece...

it is. the.drizzle meant (I think) to make the cage in two halves, put the ball inside then attach the halves together

I'd like to point out that the quality of simple mods (shape mods, etc) boil down to the level of detail and craftsmanship employed. This puzzle certainly does not lack craftsmanship and it is primarily because of craftsmanship that it deserves its praise. I think a lot of people would do well to remember that. :wink:

Couldn't agree more! I was simply pointing out something that seemed pretty obvious, but it looks kind of like a dick reply--not the intent at all! And I think that's the second time this week that I've done that--lousy internet not conveying tone...

(For the record, I'm with the impressed group on this puzzle)

Oh yeah, this style of mechanism can be used to make all kinds of stuff, including really difficult to make things like the pentultimate. The fiddle factor on the ones with lots of pieces is extremely poor though.

OK, I have clearly REALLY missed something with this puzzle; can you elaborate please?

(I really wish I could understand cyrillic, it would make life so much easier...)

If, as flambore suggests above, there is no internal mechanism and it is held by just the cage, puzzles like the Pentultimate that are hard to hold together from the inside loose all that complexity. But, as Bram notes, they gain the problems associated with a cage designed to hold the pieces together.

I imagine such a puzzle would want internal ball bearings to click stop at aligned positions like a Skewb.

A note on the craftsmanship: Aside from the interesting mechanism, this puzzle tackles the two very difficult problems of concave and convex surfaces with excellent results. I am guessing it is paint, but the results look almost like stickers. An incredible job that can be lost when considering all the other interesting aspects of this puzzle.

(Getting WAY off topic here, but you get that...)

Ah! That makes sense; get around the complexites of holding something like the pentultimate / little chop / whatever-deep-cut-symmetry-you-want together via a convoluted internal mechanism with a simple external cage instead! What a great idea--making a spherical version of whatever puzzle you want would be very simple with this approach, craftsmanship notwithstanding of course.

I love it!!!

I am afraid this approach is kind of restricted.
A 3x3x3 without internals inside a cage seems impossible to me because not all pieces will have contact to the cage all the time and can therefore fall out.

True, but a 3x3x3 is not deep cut!

You can always make the holes in the outer cage small enough that the pieces inside can't fall out. It's directly at odds with fiddle factor though.

It's not that they need to be only smaller, but small enough relative to radius of the sphere inside the cage.

For example, I'm really liking the idea of making spherical "little-chop" puzzle like this now, and if I make the sphere about 120mm diameter (which is not too much bigger than other readily available sphere puzzles), then I have quite a bit of real-estate to make a cage with 6 "square" openings for the faces of the cube.

Hmm, I may try this out next actually...

the.drizzle...

your idea for a caged spherical little-chop is great - one could print the pieces directly in 6 different colors... No stickers needed!

If you don't make it, I will! :)

Gee, had I known people would get so excited about this idea, I'd have posted about it years ago :?
