PUZZLING PENTAGONTM ...posed by Donald Knuth This 16-piece lasercut acrylic puzzle has a lengthy pedigree. From a suggestion by Nob. Yoshigahara, the well-known Japanese puzzlemaster, to the posing of 4 very difficult questions by Don, this puzzle was first distributed at an International Puzzle Party. We developed it further, adding many other designs and questions. There's always something else to explore with it. There are 4 triangle sizes each in 4 colors, which can build 4 separate little pentagons or one large one. Their geometry is related by the "golden ratio." Handy cloth storage bag and instructions are included. Recommended ages 10 to adult. (Shipping discount) |

DEKA-MOSAIKTM developed
by Kate Jones
This set is an excellent introduction to pentagon play:
Create ever-changing patterns with 15 pairs of golden
triangles and 5 pentagons in an acrylic 7" decagon tray. The
four-color mix of the pieces makes it
fun to continue to find new and different
arrangements. Colors may vary. Recommended for ages 8 to adult. |

DEKA-STARTM styled by Kate Jones
This set of two shapes in four colors is the next best thing to a kaleidoscope. The 36-degree rhombus and the 72-degree rhombus are just what it takes to fill up a decagon. Vary the patterns as you like from utterly chaotic to exquisitely symmetrical. Colors may vary from those shown and may change periodically. Recommended for ages 6 to adult. |

KITE-MOSAIKTM developed by Kate Jones
This set is the most complex of the decagon trilogy. Four shapes in four colors include kites, darts, and the two golden triangles. Kite patterns of various sizes can be formed with the colors within the tray. Outside the tray the pieces can model every size of kite, from a unit tile to a giant one that exactly uses the entire set. Build it a certain way, and you can split it to form two tall triangles. Join those a different way to form a thin diamond. We got quite a kick out of discovering these relationships, maybe because solving the shapes was really tough. Color mix may vary. Recommended for ages 10 to adult. |

LA ORA STELOTM created by Jacques Ferroul
The name means "The Golden Star" in Esperanto, and it's an original multi-polyform set based on combinations of the two golden triangles in groups of one, two and three. The 32 Lucite tiles are in 8 luminous translucent colors. Color arrangements may vary. The 12" tray's floor has 9 rings for forming ascending sizes of pentagons, rhombs, trapezoids, stars and more. Display stand included. Jacques' webpage has an awesome collection of patterns and challenges for you to see and download. Here are more details about the set, plus a prize competition. Recommended for ages 10 to adult. |
RHOM-ANTICSTM  RHOM-ANTICSTM ...conceived by Ward Hollins |
|
A dazzling decagon floats like a globe in its
23" frame, made of 90 tiles: 45 wide and 45 slender
diamonds (72 degrees and 36 degrees).  Each tile is divided through the middle into four triangles, to give each side its own color. These compartments are filled with all the combinations of 3 colors. Edgematch the tiles to create
symmetries and ribbons of color with frosted mirror
accents that give the design a metallic gleam. Once you overcome an initial sense of
overwhelmedness, playing with this set can be a
transcendental experience. Every completed pattern is a joyful new
plateau. Custom orders are invited from our extensive palette of
available colors. White or black tray looks best.$495 (plus $15 oversize shipping surcharge)
