"This puzzle is two designs in one - the cage comes with two sets of burr pieces (one a six unit length and the other an eight unit length) which are entirely different puzzles to insert. The designs were released at roughly the same time, and I found them both interesting. When I realized they shared the same cage, I was in! Both designers graciously gave permission, and so I present to you the combined Vectes / Ghidorah Box. Ghidorah is the "warm up" difficulty with a level 22.3 solution. Once...

from cubicdissection.com:Oh Tom, you crafty little devil. Once again he comes out with a very interesting and unique design that I can't resist making. Tom's Square Dance consists of nine pieces which interlock into the surrounding frame. WIth a unique level 1.8.5.3.4 solution, this is a tricky nut to crack. Simply identifying piece positions is quite tricky, and sorting out the insertion order and moves necessary simply compounds the difficulty. Definitely doable, but definitely difficult. I'm ...

from cubicdissection.com:I was showing various puzzles to an IPP attendee when they skipped right over this one. I started to show it to them and they said "Everything interesting that can be done with 4x4 cubes has already been done". I laughed and showed them about half of the solution, at which time they cried "Stop - I'll take it!". This really is a fabulously interesting cube, and Tom really hit the ball out of the park with it. It's just a downright fun puzzle that still puts a smile on my...

This is a 20 piece altekruse type puzzle of unknown designer. J. McFarland modified it with extra internal notches to allow a 6 piece burr to fit inside. The puzzle uses 1" sticks and the 6 piece burr is a level 5 Bill's Baffling Burr designed by Bill Cutler. Both puzzles were made in 1988, only 2 sets made. 8 pieces need rounded edges in the notch for the puzzle to assemble.

"Despite the devilish difficulty of this puzzle, let me assure you that Derek is a really nice guy. Keep that in mind as you go crazy trying to solve his latest creation. Derek's half dozen is fiendishly difficult at a level 26.9.5 solution. It's so hard to solve I took pity and made the pieces from three woods so you'd have a big clue as to what goes where. I'm also shipping it assembled. You're welcome.Construction is dead on with VERY nice tolerances. Everything's square and beveled, with thr...
