Click a thumbnail to see its larger version and description.
A Square-1 transformed into the shape of a tetrahedron.

Another shape transformation of a Square-1 by Anthony Greenhill. He decided to modify not the Square-1 itself but a Square-1 in midturn. That is the reason why the two long blocks (representing the middle layer of the Square-1) are oriented nearly orthogonal to each other.
This puzzle was made by hand with applying plastic sheets to each part of the original puzzle. Buliding time was 70 hours split about one month.
Edge length: 135 mm
