John Montroll is a design genius:

In his book “A Plethora of Polyhedra” he explores the complexities of single sheet 3d-shapes, and this rather splendid prism caught my eye as something I wanted to try.

I like how the pre-folding teases of open edges up and inside the finished shape which locks itself – very clever Mr Montroll

There are some eye-poppingly complex polyhedra in this book, I shall be trying some more I think.
