This is the 9th in my series of increasingly deeper cut face turning icosahedrons.

In the face turning dodecahedrons, as the cuts get deeper than a Megaminx, the centers shrink in size and the slices begin to overlap each other on the edges, creating new parts. Aleh's Brillic, also known commercially as the Pyraminx Crystal, was the first example with cuts at just the right depth to make the face centers disappear.

The Radio Crystal is a face turning icosahedron, with the same property that the cuts are at just the right depth to make the faces disappear. Surprisingly, this has already happened once before with the three faces around the turning face on the Radiolarian 2. But the cuts on the Radio Crystal are so deep that they pass another set of face centers on the icosahedron- 6 more per face! Buried beneath each hidden face center, there is a stack of centers 3 deep, one fixed to the core, and two with with holes to allow a screwdriver to reach the screws inside.

Visually and conceptually to me, this puzzle is the closest icosahedral analog of Aleh's Brillic and Praminx Crystal, so I've named it the Radio Crystal... aka Jason's Brillic.

Turning quality is very good. Criticisms from me are that it is a bit squishy due to the acute angles, and that the brillic pieces sometimes trail slightly behind a turn and have to be aligned separately.

Wow. Just freaking wow.

This looks so good! The face patterns look like a sunburst. Gorgeous!

I want one!
Is it going up for sale on Shapeways?

That is awesome! I'm really liking this series, and can't wait to see the rest in it.

-Mark-

The time and money you have put into making this series is astounding. I can't wait to see a family picture when they are all done. I wish i could afford to buy them all

Beautiful!

Man, these are looking great! Hope you go all the way and make an icosahedral Chopasaurus!

Great puzzle, and a very apt naming.

-Doug

This is by far my favorite series. I can't wait to see it complete.

These are all amazing Jason.

BEAUTIFUL puzzle!

I just want to thank everyone for taking time to post some nice words. I'll use them as fuel to keep going! 6 more...

Kevin, this one is a likely Shapeways candidate. It is stable and turns nicely, so it might be nice. Unfortunately the innards are stuffed with mech, so it isn't cheap. And also I'd want to fuss over a few minor tweaks and make an more polished design.

Thanks again everyone!

Haha. That sounded to me like you were saying that there are 6 more puzzles of this type with deeper cuts to come.
What did you mean?

I can't wait for the chopasaurus equivalent. Honestly I beleive you could make it there. After what you've acomplished, you are the man for it.

Gorgeous ... simply gorgeous. Great Job!!!

Carl

Yes, there are six more!

By the way, when I was designing this one, it was during my trip to the IPP, and I flew Delta Airlines. I did a double take when I saw that the Delta logo has parts of the Radio Crystal!

Mind blowing.

your entire set of icosahedra puzzle is plain fabulous ! Any chance some of them will ever be mased produced ?

Incredible. This might be my favorite twisty puzzle of all time.
