W72 Small Dodecicosidodecahedron

W73 Dodecadodecahedron

Large light green decagons, blue pentagons and pinky triangles:

 

This one’s rather like the Small Cubicuboctahedron (W69), but this one is based on an Icosidodecahedral rather than a Cuboctahedral structure – so although the basic structure is the same there’s rather more to it. The triangular pieces have deeply re-entrant spaces under them, so it’s quite a structural engineering challenge to build it!

The triangles and pentagons are particularly clear here, sitting above the light green decagons – making a lovely shape from simple parts. And as before, there are lots of other chopped out forms yet to come, including the Small Rhombidodecahedron (W74).
