# Products Related to Fractals

 HexaPlex \$39.95 "HexaPlex" is the world's first true fractal puzzle. With this unique puzzle, students and other puzzle lovers can actually build a fractal with their own hands. This magnet-backed foam puzzle contains only one shape, but in five different sizes, with over 270 pieces in all. Following a simple set of rules, iterative placement of the different size pieces builds an approximation of a infinite fractal. Different matching rules result in different fractals using the same set. A 12-page instruction pamphlet, including 9 challenges and 3 copyable worksheets, comes with the puzzle. Ages 8 to adult. Fractal Trees \$19.95 In this book, by combining photographic imagery with iteration, the mathematical process at the heart of fractals, Robert Fathauer explores his unique vision of a nature that is even more fractal than the real world. These creations include a fern-like tree built from the stem of a rose bush, an infinite collection of spirals formed from the skeleton of a cholla cactus, and a tree whose outline resembles a maple leaf. Thirteen different trees are shown in two page spreads, and six randomized fractal trees are shown as well. The book also includes a section on the method used to create the trees and notes on the individual trees. Included are three classroom worksheets that teachers can copy, covering branching of fractal trees, trees in nature, and infinite series. By Robert Fathauer. 52 pages, 8-1/2" x 11". Fractals in Our World poster \$11.95 Poster with a number of photographs illustrating the role of fractals in natural and manmade objects. Comes with an 8-page lesson guide, including four reproducible worksheets. 22" x 34". Bats and Owls Poster \$8.95 Black bats and white owls fit together in intricate patterns. Instructions relate the design to the scaling of triangles, infinite series, and singularities (points at which tiles become infinitesimally small). 22" x 26", by Robert Fathauer. Fractal Serpents Poster \$8.95 Two-headed serpents intertwine in complex geometries. Instructions relate the design to infinite series, self similarity, and fractal dimension. 16" x 26", by Robert Fathauer. Self-replicating Dragon \$8.95 A fanciful dragon is the theme for this self-replicating tile - one that can be subdivided into exact replicas of itself. Instructions relate the design to self-replicating tiles, the use of iteration to solve mathematical problems, and fractal dimension. 20" x 22", by Robert Fathauer.
