Inversions: Catalogue of Calligraphic Cartwheels

Word Designs Demonstrate Symmetry Introduce your students to the basic concepts of symmetry with more than 60 mind-boggling lettering designs by Scott Kim, whom Isaac Asimov called "the Escher of the alphabet." Each word in Inversions exhibits striking geometrical symmetry. For instance, the word mirror is written with reflectional symmetry; symmetry reads the same upside down; and infinity spirals off to infinity. The accompanying essays connect mathematics and symmetry with art, psychology, and music. One of the sections shows students how to create their own inversions.
