Kevin Sadler wrote about it:“My copy of Tulip 1 is made from a vibrant red Padauk and contrasting Wenge. The name seems to allude to the shape of the opening in the box. At first glance, it appears like a standard 2x2x2 shaped gap but after a moment of play with the puzzle, it rapidly becomes clear that the opening is severely restricted by a diagonal segment covering 2 of the interior corners. Osanori has used this method of constraint quite a lot over the last year or so and it really ups th...

From Wood Wonders - "I have been wanting to make this one ever since Alex sent me the design. He has just been producing so many cool designs lately, it took me a while to get around to it. Pillar is four pieces that must be inserted into the unique box and they fill the openings completely.I had acquired some very nice holly and wanted to set off the face of this box with it. The woods used for this box are especially nice. I really love the Pistachio wood. I managed to sang a few small pieces...

         I recently decided to make a run of these cool puzzles, they are not quite interlocking so I included a tray to display the puzzle.  Not an overly difficult design but you can certainly see Stewart’s progression over the years.  This puzzle led Stewart to one of my personal favourite designs, ‘Four-Piece Interlocking Cube’.I made several different wood varieties for this puzzle design, a few in one wood and a couple in multi-woods.They are lacquered and given a coat of Co...

From Pelikan - “2D and 3D packing problems are my favourites, especially those with only a few pieces, together with a sufficient level of difficulty. I hope you will like Pincers and add it to your collection. You do not need to create the illusion of a full cube inside (like we all do with amazing packing designs by Osanori). Just fit the three pieces below the top layer. So what is the clue here? – the shapes of the pieces and box opening. Study them well to eliminate a huge number of po...

Designed and first released at IPP in 2009, Surround is closely related to the 3/4/5 cubes designs by Ichiro. In this case, six pieces must be used to surround the solid cube in such a way that is self-supporting. Two solutions using magnets are possible, with another "rule-breaker" solution that does not use magnets and covers the cube completely! The finished shape is pleasingly symmetrical and displays well.************************************************************For multiple items, combin...

Here is his latest "Inelegant" offering. Inelegant Snakes uses the offset L piece that was used in his Snake Pack design. Except this...

I only ever made two of these puzzles for the IPP Design Competition (San Francisco) in 2009.  It’s a fun puzzle that can be very confusing to assemble from pieces even if you see the assembled shape.Several years ago Scott Peterson (at my insistence) made a very nice run of them and later Tom Lensch (at John Rausch’s insistence) made a run, with some featuring Holly, Ebony and Rosewood!I recently was able to acquire some 1/2” size stock and decided to make a few.  This can be consider...
