Open Window, design Tom Jolly, made by Tim and Carol Udall. Four pieces in a frame; take them out or put them in. Made of Sapele and Yellow Birch. Not a terribly hard puzzle, but has a satisfying solution. Harder to put together than take apart, so if you want it shipped disassembled, let me know.

This was a prototype that I made up to investigate the design...only made a few, one for my collection, one for the designer, and a couple which I'm selling here. I have no plans to produce this puzzle in the future. It is signed and dated.This burr is 11 pieces with a single level 2.3.1.2.1.2.1.1.2 solution. It's tricky but doable! Crafted from solid yellowheart with very nice tolerances, intentionally a little loose in this dry winter weather to ensure proper operation during the more humi...

Take apart - disentanglement puzzle from Lambert Bright. Pretty amazing amount of work and detail went into this puzzle. It comes very nicely packaged in a tin with graphics. Inside there is a leather pouch with an impossible braid you have to solve to access the actual puzzle inside, which is heavy bronze. VERY nice job. This item is from my personal collection. Shipping is $8 in the US for Priority Mail. International shipping is $18 for first class and $35 for Priority Mail. I will comb...

From Eric Fuller's description: This clever puzzle shows major design chops. Using four identical, simple pieces and a cage, Yamamoto created a level 9.2.5 beauty with only one solution. Definitely one of those "Why didn't I think of that?" situations; I am nevertheless privileged to make it, despite not being clever enough to think of it. Fun to solve, a nice half hour challenge for the serious puzzler. Maybe 5 minutes if your name is Oskar. > I could have glued the cage together from ...

Eric was searching for some new designs to make, and wandered over to Ishino's site. It had been a while since he checked, and he found that Chomine was putting out some interesting creations using internally studded frames and notched sticks. He chose several designs which he felt gave a good sampling of appearance and difficulty, and emailed him for permission. Stéphane agreed!Three sticks trapped is the simplest of the Chomine puzzles this batch, but it may be the most satisfying. With a uni...

from puzzlepalace.comThis puzzle is a collaboration between me and Oskar van Deventer. My idea involved two pieces, where the pins of one piece connect to grooves in the other piece and vice verse. The grooves in both pieces should form a maze pattern. After some failed attempts, Oskar simplified this idea to the extreme. Each piece should have just a single pin and a single meandering groove. This way, the puzzle effectively turned into an N.G. de Bruijn "Beer Bottle Problem", see page 373 of "...

Not actually sure what he called this one...it's not listed on his site anymore, and I don't appear to have an instruction sheet for it. "William Waite" is laser-engraved on the inside of the tray. One of his many, many laser-cut tray puzzles.

Kitchen Floor puzzle from William Waite, 1998. I don't appear to have an instruction sheet for it. "William Waite" is laser-engraved on the inside of the tray. One of his many, many laser-cut tray puzzles. You're supposed to make a symmetric design with the holes; there are some notes about this on William's website. Despite there being LOTS of solutions, it's pretty difficult to assemble. I was happy to assemble it without symmetric holes. Puzzle weighs under 3 ounces.
