A Square-2 with pieces which were further split up.
The Square-2 is an unbandaged version of the Square-1. The larger pieces are split up which makes it equivalent to a dodecagonal prism.
The Square-3 walks this way a step further. Here the pieces at the edges are split up too. This changes the puzzle back into a puzzle which behaves bandaged. If one wanted to further unbandage this puzzle the result would be equivalent to a tetraicosagonal prism.
The first version was presented in May 2008 here on the forum but the inventors name is so far unknown.
