Here's some more Geomag things, this time in a different setting.

The problem with reflective objects is that you need something behind 
the camera to be reflected, and I'm just too lazy. I have created a very 
simple room, few of the objects have any detail in them as they're not 
meant to be seen directly. It could probably do with some more things in 
the room.
There are 2 area lights, 1 spherical one inside a blue lampshade and one 
outside a window illuminating some closed red curtains. Radiosity does a 
good job of filling the scene with light. It took nearly a day to render 
at 2560x1440.

On the left is an icosahedron, with points added. I think I should have 
stuck to plain colouring, it's a bit too busy.
Next is a double sized icosahedron in 3 colours to show up some of the 
symmetry.
The next object is the same, but with different colours and the 
pentagonal points turned inside out to form an icosidodecahedron.
Sticking some points on it results in one on my favourite Geomag shapes, 
here on the right. It uses 180 rods and 62 balls.

I think it's worth noting that if you scale the second shape up to being 
3 rods along each edge, and turn the pentagonal points inside out, you 
end up with a Geomag representation of the buckyball! 270 rods and 92 
balls required.
