Every letter and number in this font can be folded from one universal
hinged chain of pieces, specifically 128 right isosceles triangles
hinged at their sharp corners. In particular, every character has
exactly the same area. In addition, the chain can fold into a square,
represented by a period. See our paper
“Hinged Dissection of the
Alphabet”, *Journal of Recreational Mathematics*,
31(3):204–207, 2003.
