Created for Key Curriculum Press as a gift to Tomoko Fuse, 1996.
Tomoko Fuse (the last name is Japanese, pronounced with two syllables) is a master of unit origami, in which many squares of paper folded into simple identical units interlock to form intricate polyhedral forms. Her book Unit Origami is published in the United States by Key Curriculum Press, a leading publisher of books and software for mathematics education.
For this design I made letters out of the most common unit origami unit: isosceles right triangles in alternating colors.
