HelicosahedronA Helicopter Cube truncated into the shape of an icosahedron.
Icosa-1A Square-1 transformed into the shape of an icosahedron. Compared with Greenhill's icosahedron it is slightly "axised"
Icosa-4A 4x4x4 in shape of an icosahedron.
Icosa-5A 5x5x5 in shape of an icosahedron.
IcosacopterThe Icosacopter is a deeper cut edge-turning icosahedron. It is deeper cut because the center pieces (the middles of the edge) are in no way able to connect directly to the core. Made by Sharon Avidor and Matthew Ray.

Icosahedron ImpossiballCreated by Anthony Greenhill. Having never seen even pictures of another one before, he wonders if his is the first in existence.
IcosaixA face-turning icosahedron. Not the first one but the first to reveal the jumbling geometry of this type of puzzles.
