Face-turning icosahedron
Above:Jürgen Brandts version - Solved
Click a thumbnail to see its larger version and description.
The first known face-turning icosahedron. The first version was made in 2003 completely made by hand and from scratch.

The icosahedron is the most elusive of the platonic solids. Only few puzzles are transformed into this shape. Equally few puzzles exist with its axis system. The first known sample of a face-turning icosahedron was made by Jürgen Brandt. The exact date is unknown but it was no later than 2003. He could not start with a mass produced puzzle because there had never been a puzzle with this axis system by that time. Jürgen therefore created the puzzle mainly from cardboard.
It works but the creator himself called it "unplayable".

The images #3 and #4 show a better working sample made by Claus Wenicker in 2013.
