Seashores Icosahedron

Spent last night constructing a Regular Icosahedron from a beat-up copy of A Golden Guide: Seashores. There are some lovely bivalve diagrams.
The instructions were in Unit Polyhedron Origami by Tomoko Fuse.
I have a falling apart Essential Fantastic Four Volume One
that is just screaming to be turned into a 90 unit Truncated Icosahedron.
