This original design is brought to you by Martin Raynsford and was originally funded through a Kickstarter campaign. There are several fiendishly complicated tray puzzles based upon space filling fractal curves.
Dragon Curve: first investigated by NASA physicists John Heighway, Bruce Banks, and William Harter. It's rounded flowing pattern and nearly identical pieces make it the hardest of the different puzzles.
Made from a high quality birch laser plywood sheet, the natural look of the wood will show natural colour variations. The material is sanded and oiled to create a superior finish. Some of the puzzles have been dyed with wood dye. The name of the puzzle is displayed on the front, while the designer is displayed on the back.
