Gyro expanded truncated cube
Hi,
I'm fascinated by the Stewart Toroids, and guided by the library in Great
Stella I built this gyro expanded truncated cube with Polydron.

James,
I've never really paid them much attention, but having read your post, I thought I'd take a look with Stella (it great for just playing around, isn't it ?) and I can see the attraction.
I'd never heared of Polydron before (see what a sheltered life I lead ?), so I took a look at their website. It seems a bit expensive, given that it is made of platics, but I suppose it a niche market. I might get a bucket for my daughter.

It is used a lot in schools in the UK, I heard about it through my better half who is a teacher.
I have been able to find new sets at 50% - 75% of full price by watching eBay UK for a while.
The open-centred pieces, called Frameworks, are cheaper than the filled-in ones. They are also slightly thinner so they can be hinged to a tighter dihedral angle (about 42 degrees) before starting to separate.

There are quite a few similar products around. The only ones I've had direct contact with are GeoShapes, aka GeoAustralia, and GeoMag. The former snaps together while the latter is magnetic. Both have hollow transparent faces with panels that fit in, which makes them a bit different from Polydron, so it just depends what you like.

I agree that paper models are ultimately the best, but they do take longer to make of course.
And yes, I used Stella to create the model in my avatar and print its nets. Read about that model here:
