Annapurna (also known as ten intersecting triangles or 10 × 3 × 1 polypolyhedron) was designed by Robert Lang, but the model presented here uses my Sturdy Edge Module rather than the module described in author’s original instructions. StEM can be used as a replacement in this model because it has the same 90° angle at the tip and results in the same width-to-length ratio as the original unit when folded from 4:1 paper.
The straight-down angle in the first picture shows the dodecahedral symmetry of this wireframe polypolyhedron as well as the small woven icosahedron hidden below the tangled layer of spikes.
