HEXACUBE
... handcrafted by Kate Jones

The 166 different shapes of 6 cubes joined, plus 4 unit cubes, are built into a 10x10x10 cube, in a hinged fold-out wood box. The pieces are sized to Quintillions and Super Quintillions. In fact, they are constructed from the parts of 10 quint sets and at least 4 superquint sets. Each piece is carefully tailored to fit easily and smoothly with any other piece, no matter how convoluted the combination. Over the years many interesting questions have been proposed for subsets of Hexacube, and for long blocks other than the 10-cube to build from the entire set. The owner's manual includes a naming system and one solution to the 10x10x10. Exploring other sizes is up to you. When ordering, please allow at least 4 months for Kate to build your Hexacube. $795

invented by Piet Hein, produced by ThinkFun, Inc.

The immensely popular 7-piece Soma cube of decades ago has been brought back by the ThinkFun (formerly Binary Arts) folks under this new name. It's made of molded plastic in a nice handling size and fits well in all those three-dimensional shapes. Soma expert Sivy Farhi contributed much research material. A deck of puzzle cards with hints and solutions will keep you pleasantly challenged for a long time. The graphics are great. Recommended for ages 8 to adult. $12

Polyominoes
... the definitive book by Solomon Golomb

This is the new edition of the original, definitive polyominoes book, more than a quarter century after its first publication.
