Winston Freer Tile Puzzle Trick by Winston Freer


Sample Piece
Sample Piece

Designer: Winston Freer

Size: 29x24x2cm

Notes: The Winston Freer Tile Puzzle Trick is a modern classic of puzzling mathematical magic. The trick is performed by successively removing three one-unit blocks, yet each time maintaining the overall dimensions of a 9x7 rectangle. However, unlike the Curry Paradox, on which the trick is based, the pieces fit perfectly (no hidden gaps) in the 9x7 tray both before and after the trick is completed. Some pieces show significant wear. Included 4-page instructions for presenting the trick (see video).

Undocumented provenance: this mechanism was originally owned and used by world-renowned magician Lennart Green, and was subsequently given to G4G-founder Tom Rodgers.

Est. value: $100

Winning bid: $118

Lot Closed

Morph II (O'Beirne's Cube) by T.H. O'Beirne / Pelikan (pieces), Buttonius (box)


Assembled

Designer: T.H. O'Beirne
Maker: Pelikan (pieces), Buttonius (box)

Size: 6x5x5cm

Notes: This is an elegant puzzle and presentation, with an intriguing back-story. Peter Hajek's notes:

In 1961, Thomas O'Beirne described in his New Scientist column (224, 560-1) a fantastic cube dissection. Six irregular pieces formed a cube and five other different rectangular cuboids. Surprisingly, it went largely unnoticed, probably because of difficulties in making the set. O'Beirne did not include it in his 1965 book Puzzles and Paradoxes and it remains little known and appreciated.

I got interested in this puzzle via my earlier encounter with its much simpler but very pleasing pre-cursor which first appeared in the book Matematiceskaja Smekalka (Mathematical Know-how) by B. A. Kordemskij published in Moscow in 1954. The readers were challenged to cut an 8x8x27 wooden beam into four pieces which could then be assembled to form a cube. The solution consisted of pieces which could be morphed by simple one-step shifts into a cube and two other rectangular cuboids. I designed a box with three receptacles and some additional tasks to package this as a mechanical puzzle. It was produced commercially by RBA as the Morph Puzzle in 2006.

Morph II is the result of an attempt to do something similar with O'Beirne’s dissection so it is translated from a geometrical curiosity into a mechanical puzzle, and reaches people who will appreciate its elegance. I designed this presentation, Peter Knoppers helped with the construction of the box and laser-cut it and the New Pelikan workshop made the puzzle pieces. The non-morphing cube solution was pointed out to me by David Singmaster.

The six pieces can construct 6 different shapes (the cube two different ways). The box, when constructed, will have 6 different template rectangles on its faces, giving implicit and unique instructions for each of the target shapes. This was Peter Hajek's IPP32 Exchange puzzle.
