With a Zometool building kit, you can construct every shape possible -- from a high-rise to the structure of the next vaccine. Each spherical base unit has 62 slots. The slots are three different shapes--triangles, rectangles and pentagons--and each shape has a corresponding stick that fits into it. Because of the angle and proportions of the pieces, you can build mathematically perfect ice crystals, Archimedean solids, or viruses. Nobel prize winners have used previous versions to model their concepts. The Design Series nixes the primary colors, standing in classy black and white.
