About 25 years ago, I found Doug Engle's Circle puzzles - flat versions of Rubik's Cube. I thought I understood the puzzles completely. Then Doug came out with puzzles where the orientation of each piece mattered.
Click here for some examples.
Vishnu Chaitanya Pedasingu has now come out with a nice set of versions of these puzzles. Good interface. Try the free version.
