I'm very proud to present number seven in my series of "Radiolarians", or face turning icosahedra.

This is an even deeper face turning icosahedron than the Radio Web (Radiolarian 6). No new pieces are added for this puzzle. They are only removed as the cuts get deep enough to hide them. You could say Radio Web is an "in-between" from 5 to 7 which contains both their pieces.
But as this puzzle simplifies relative to Radio Web, it gets a really beautiful pattern.

I'm naming this puzzle based on the Jewel Spider, which has an abdomen reminiscent of the sticker pattern here. Check out the last few images to see what I mean.

Also notable, is that this design gets some nice regular triangles again, which we've missed since number 4. (Eitan's Star)

This is the second time I have attempted this puzzle, having designed and printed two separate designs.

This puzzle can jumble in two ways again, and I've included closeups below of the jumbles.

Video is here.

Movement quality is very good.

Thank you!

Wow. Absolutely gorgeous. Those opposite cuts are getting closer and closer together!

What a beauty! I'm pretty sure it's the icosahedral equivalent of Luke's Novaminx. The jumbling is quite fun.

Wow, you're right! Seems to be the same pieces in the NovaMinx. Looks amazing, Luke.

Now that is thing of beauty and an impressive mechanical design. But what a beast to solve! Well done.

Very nice puzzle !!!

Can you show us pictures of the spider in a jumbled state ?

Extremely Beautiful! Either the puzzle or the photo!

Face Turning Isocahedron......I only know the "Eitan's Star" Version. Seems there're more possibility for FTI.

Beautiful face pattern!

Gorgeous.

I like this one much better than the previous one, I think.

Jason, I have a mechanical question. For the small edge and the 4 chiral triangles that touch the edge... Is it easy to twist the edge in place? If not, after you do the shallow jumbling so you have two (rchiral, edge, lchiral) groups that have been reverse so the edge and chiral pieces are sticking out, can the edge easily be twisted? Also, is it somewhat easy to partially twist in place the chiral triangles into their jumbled state?

I've found on the Novaminx that you have to be careful when the puzzle is jumbled that you don't accidentally twist the edges or chirals in place and also that a catch on an edge or chiral won't force it to twist if you push through the catch. The problem is minor but definitely there.

What can I say?
I am in the strange situation that I want to say something meaningful and/or encouraging but all I can say is:
1. Very good!
2. This is the 19th puzzle with this axis system. The list grows!

In addition I want to say something which does not deal with the puzzle itself.
I highly appreciate the work you put into your images.
Sadly the parts of your puzzle with greater distance from the camera are rather blurry.
I make my photos from long distances with zoom and a stand to avoid this.
BTW: I have seen many worse images than yours. But because of the work you put into your images I thought you might appreciate such criticism.

Absolutely fantastic Jason! My favourite Radiolarian of them all! This puzzle really is excellent, and considering the complexity of the puzzle, it turns really well. I would love to compare the mechanism with the NovaMinx.

The problem is the gaps hidden underneath the corner pieces (you can see the gaps in the 7th picture). There is no (practical) way to get a piece in there with any sort of mechanism, and so there is a gap, which the edge pieces can use to rotate in. Obviously I don't know if Jason's Radio Jewel's edges rotate, however if they don't, I suspect that is due to being at a fairly tight tension, for which the NovaMinx was not (I shipped the NovaMinx somewhat loose, however I am confident that the problems with edge and chiral piece rotation can be solved by tightening the puzzle a bit).

Once again, excellent puzzle!

The edges and chiral triangles don't twist when I'm turning the puzzle. And I was all prepared to say they're tough to grab and turn, but I was able to turn an edge just now. I think I agree with Luke-- I've got it dialed a little loose right now and the puzzle turns well. Cinching up my make the edges harder to rotate, but it hasn't happened to me yet.

I can't twist the triangles into their jumbled state.

It is tough because the edges need to grab onto those chiral triangles which doesn't leave a lot of room for a reasonably sized puzzle.

I wonder if there's another version of this where the edges can somehow root deeper, but I feel like I tried to find that already.

I did place internal blocking pieces to either side of the edge before and I didn't like the turning as much. I could see if it helps prevent the twisting.

Ah well, I'm still quite happy with it mechanically considering the size!

Andreas-- you are right-- I was playing with opening up my aperture in these photos. It was fun but I see they'll be hard to trim. I'll be more careful and slightly less artistic next time.

Jason this is your best one. I will buy it!!!!!

Very beautiful puzzle! I'd love to have this one in my collection

Thanks a lot everyone! I hope to sweep through my radiolarians and offer them if there is interest. So I'll try to clean this one up for sale soon.

Thanks again!
