More complicated burrs. You can recognise Bill Cutler's Wausau models
and other burrs. There are many models invented by Oskar van Deventer
and made by Jean Carle. Wayne has made some burrs and even I have made
some of them. Note also the traditional Russian burr.
Same case from the other side.
Cube-packing and other packing puzzles. Trevor Wood, Allen Rolfs, Jean Claude Constantin,
Dario Uri and I have made these puzzles.
