This is the discontinued Burry Joint puzzle, designed by Bill Cutler and crafted by Jerry McFarland. Puzzle will ship disassembled with an original paper assembly diagram.

Box Frame. This has 4 pieces, made from bamboo, with dowels in the corners to give it some strength. There is only one of these; I designed it and made only one copy. It would be a level 17 if you took it apart orthogonally, but I think it's about a level 9 using rotations. Not super difficult, but not easy either. Doesn't go together the way you think it should, though there are at least 2 solutions using orthogonal movement.

This auction is for a group of three puzzles. One is an Obsivac Hedgehog. The fit isn't perfect. The one on the right-rear is an Arjeu CT28; there's a teeny chip out of one of the ends of the pieces, and the key-piece is a straight stick through the middle with no notches. Does NOT come with the original box.The last one is a yellow plastic star, but each of the 6 pieces is split lengthwise in 2 for a total of 12 pieces. Makes it much harder to assemble.

This is one of William Waite's puzzles, out of production, called Puzzling Zoo. As you can see, it's a nicely done laser-cut version of a nine-tile edge-matching puzzle with little wooden animals to hold together each edge. Defect; there's a very tiny dimple (size of a pen tip) on one side of one of the tiles. The puzzle measures 6" on a side, 3/16" thick stock.

Caged Knot from Pelikan's shop. 3 "knot" pieces in a cage, level 13.2, the highest level of this piece configuration, according to Ishino's site. This is a really fun puzzle to play with and it's very well made (it's a spare copy...no way would I sell both!). I think there were about 80 copies of this made, originally. Naoyuki Iwase did a short run of these, too, but with an extra variant piece.

Magic Fish, IPP29 Exchange Puzzle. 3 pieces with semicircles attached on the bottom layer can slide around, allowing the upper layers to make 3 different images of fish. Artificial movement restriction that pieces may only turn to the right. Designed by Tsugumitsu Noji. Puzzle is signed on the back in Japanese and English. Nice little puzzle.

Packuliar has 4 pieces which pack into the box. It's fairly difficult; a rotation is available, but without it, it's a level 7 puzzle (if I remember right). Even with the rotation, it's not easy to figure out, but it isn't insurmountable and is fun to play with. Eric made 26 copies of this out of maple, bocote, wenge, purpleheart and paduak.

This is, for B&P, an amazingly well made trick opening box, well above their usual standards of workmanship. This is a copy of an Allan Boardman box from IPP24, very close to the same dimensions but without the extreme detail Allan always provides. Not surprisingly, they spelled his name wrong (Alan) on the instruction sheet for the puzzle.

One Piece Puzzle - a bit of a misnomer, as it is no more a 1 piece puzzle than is a Rubik's Cube. A number of bent "L" shaped metal pieces articulated by links of plastic. You are supposed to either flex them all out flat or make a cube out of it. And yes, there is a bit of a trick to it (I never did get the "cube" part of it). Exchange from Harry L. Nelson , concept by Engel. Not sure who made it, though.

Self-Referential Panels by Harshbarger and Huang. "Arrange the 9 tiles in a 3x3 layout such that each tile describes the 9 colors in its position on the other tiles." The instructions are a bit more involved, with examples, but that's the basic idea; each tile has color-information that relates to its position relative to the other 9 tiles in the grid. This is one of the stranger puzzles I ran into at IPP. Nicely made from solid plastics, with a plastic layout sheet.

This is a very nice little "fit the pieces in the tray" puzzle, called "Puzzle for Daughter" designed by MINE for the IPP29 puzzle exchange. There are 3 challenges; fit all 5 pieces in the tray (includes the two circles), or fit the three characters in the tray so there is only space for one disk, or fit the characters in the oval tray so there is no room for any disks.

Shaka-shaka is almost a cross between the Minefield game and a geometric-shape making puzzle. The numbers on the board indicate how many pieces are next to that space, and in the process of putting the pieces down, the resulting light-yellow areas are supposed to make squares or rectangles. The set has 8 different puzzles in it, and it says the pieces are from Mosaica by Orb Factory. They're somewhat like foam board, but much denser and sturdy.

This interesting puzzle features 9 tiles of "grass" and 9 snake segments which are to be arranged in a continuous snake-like line without actually touching any of the blades of grass on the nine tiles. This, of course, means finding the right configuration of the snake so that it will fit neatly on the 9 tiles, and arranging the 9 tiles so the blades of grass do not interfere with the snake's body. It's not easy.

This little variety-pack of puzzles includes the Modus Puzzle from Lagoon Games, a colored-peg set where you try to arrange the pegs so there's no common color in the vertical, horizontal, or diagonal lines, and includes some other puzzles. The pentomino set is the "Wisdom Puzzle" and can make cubic forms, and includes a number of other puzzles on the instruction sheet. Lastly, there's the Bullseye Puzzler by Setko, copyright 1964. Jump the pegs, remove them, leave one in the middle. Box has tap...

These are two variations of my Lattice puzzle that Eric cut for me during the prototype phase with different colors. The black one is smoky gray, semi-transparent, with a nice, tight fit. The red one is solid red and the fit is somewhat sloppy. These are identical to the clear Lattice puzzle I used as an exchange puzzle for IPP29, but are, to my knowledge, the only ones around in these colors (unless Eric made a couple for himself).

Not really a "dexterity" puzzle, more of a "balance" puzzle. Designed by Oskar and Wayne Daniel, made by Wayne Daniel. I never solved this. It's an odd little bit of geometry (one piece) that you are supposed to hang off the edge of a table, selecting a side/position where it is certain not to fall off. It says it has 12 possible orientations, but only balances in one of them. "Oskars's original had 24 orientations, only one of which balanced, and was called 'Cliff Hangar'." He designed a later ...

TriGears. Three gears that can be snapped out of their frames, so that the teeth can be interfaced in different arrangements. This is required because the teeth are of varying thicknesses. The goal is to "engage the three gears so that they spin freely without jamming". It's quite difficult, since all three gears interact simultaneously; you can't just try to solve 2 of them then add the third. Designed by Bram Cohen and Oskar van Deventer.

Black or White, designed by Vesa Timonen and Tomas Linden. This took me an amazingly long time to solve, considering that it's relatively simple (but non-intuitive). The instructions, though simple, can be a little confusing; I think the distinction between "square" and "rectangle" and "square with internal voids" is very ambiguous. One of the included puzzles is to "make a 8/9 sized square on the table", so does this mean an 8x9 rectangle with or without voids, or a square that's a fractional 8...

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 and limits the number of 'assemblies'. This is Bill Cutler's level-7 notchable 6-piece burr design which did not have a unique solution. When made with the slanted pieces, it does have a unique solution.

This is the last of my original 5 woods spinning icosaWoods are Purple Heart, Saffron Heart, Celery top Pine, Silky Oak and Tassie Oak. Interior wood is Aromatic Camphor.Pieces are marked inside for easier assembly10 similar pieces of joined 4 tetras, awful to perfect, but fun to playThis one spins , then it explodesAnd here is my crappy U Tube silent movie, http://www.youtube.com/watch?v=YDAJzJFoLYs,,,,you get the juice of itBuyer to pay 4% Paypal and Postage
