very strange shape-shifting puzzle


There is an original John Evans jigsaw on my desk. It has 2 sides with different patterns. There are no edges - each piece can "walk" from one edge to another or diagonally or reflect across the mid-line ... the trick is figuring out which way. I should be able to move the pieces so that eventually I see the other side.

We'll see how long this takes ...
