Here is an image of the 4th stellation of the icoshedron that I finished yesterday. It looks pretty simple - after all it is only a stick model of the docecahedron - but it is a realy **** to put together.

The difficulty ...

Rob,

Thanks for the info. I'll put in on my ever-increasing list of coveted polyhedra.

Rob,

Thanks, I'll check out GeoShapes. We already have Geomag, which I like a lot, but nothing quite compares to the "fun" of a cardboard model.

Incidentally, can Stella help you to build a model like the one you use as your avatar ?

Cheers,

Pete K

Oh dear, I've been tempted...

Thanks for the hint: it was half price on ebay, although I did end up spending twice as much as intended.... Still, you can't pass up a bargain, can you ?

Its, for my daughter Maragaret, who designed my avatar (It is actually a Father's day card).

Cheers,

Pete K

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 ...

I think I meant to do this:

After much ado about nothing, I decided to abandon my previous attempt at MW 81 and start from scratch. This time I used a combination of standard and pastel colours (for the triangular faces). I also changed to Canford card; its expensive, but the colours are lovely and I was able to use two ...

I'm having 2nd (actually about 22nd) thoughts about this one, having made several mistakes:

- Not fully understanding the colour scheme. MW suggests 6 & 5 colours (i.e 5+1 and the same five). Previously, used this for the small ditrigonal icosidodecahedron (MW81) and it works reasonably well, so I ...

You idiot ! It is obvious !

Ah well, I see it now: the 5-colour arrangement for the triangular faces, just as MW said. The decagons have their own set of (six) colours. Fool.

Anyway, I found a way to map the colours: create a series of images in photoshop, consisting of the same digit or letter ...

I'm trying to work out the colour scheme (map) for the great ditrigonal dodecicosidodecahedron (MW 81). I tried viewing the model in Stella after selecting the colour scheme that matches the one used in Wenninger's book, and noting positions as the model is rotated, but I'm red-green colour-blind ...

I finished the final Isohedron today...

The one on the left has octahedral symmetry. The one on the right has cubic symmetry

A very polished result ! I've been experimenting with different types of card recently, so my final ...

:D I don't think I will build this one again, except perhaps to keep a version for myself anyway... :wink:

There is a link to a zip file containing all compounds.
This one should be included as 30A.A5xI.C2xI.mu7.off

Teun,

I love that compound of 30 cubes. I'd even be prepared to get married again if you'd give me one as a wedding present (please don't tell my wife though) . Is this something that I could derive a net for using Stella ?

Tia,

The parameter values are shown by each line drawing. They fit in the formulae in the appendix...

I used spreadsheets to do the calculations. Sadly my computer died a week ago so I will have to redo them...

Thanks for the link, but I was unable to access the post, even after registering ...

I took a look at the paper, but didn't get very far. I couldn't see a definition of the parameters a, b and c. Perhaps these are widely understood in the context - not by me, alas.

Have you considerd cheating ? I don't know how successful this would be, but you could try printing the faces at a ...
