from billcutlerpuzzles.com:Stewart Coffin started making 6-piece burrs with pieces which did not follow the normal orthogonal rules. This restricts the number of ways that the pieces can be rotated, so limits the number of 'assemblies'. I dug up a level-7 notchable 6-piece burr design from my computer analyses which did not have a unique solution. When made with the slanted pieces, it does have a unique solution.Its hard to tell from the picture, but the pieces are indeed slanted...I'm s...

This is a small but very difficult puzzle box

A small but interesting puzzle box

From the official Cubic Dissection description: All four gears turn simultaneously around their off centered axis, contained by the rotating connector rods. I saw a picture of this toy online and knew I had to make one. It turned out to be absurdly fun and addicting to play with, so I made a small batch to share with my puzzle friends. While not technically a puzzle, if you need something to occupy your hands while your mind chews on a problem, this is your best friend. Precision cut and h...

from cubicdissection.com:Tease is the first of several Cornwell puzzles I will be releasing this year. Sam uses tricky dimensions in many of his designs, by dividing the larger pieces into a much smaller common denominator. Instead of using the advantage of a smaller unit count to up the number of moves astronomically, he shows tasteful British restraint, and zings the solver with a surprising twist. Tease is moderate in difficulty, yet fun to solve and displays very well. Five...
