Mathematical and Puzzle Fonts

Below are three mathematical fonts, inspired by mathematical theorems or open problems. The latter two are also puzzle fonts: in one form, reading them is itself a mathematical puzzle.

All fonts are available to play with as web applications which run entirely in your (modern) browser, including iPhone and Android.

Hinged dissection font by Erik Demaine and Martin Demaine, 2003.
Mathematical property: there is one hinged chain of (128) pieces that can fold into any of the letters in the alphabet as well as a square.
From the paper “Hinged Dissection of the Alphabet”, Journal of Recreational Mathematics, 31(3):204–207, 2003.
Based on a theorem from the paper “Hinged Dissection of Polyominoes and Polyforms, Computational Geometry: Theory and Applications, 31(3):237–262, 2005 (originally published at CCCG 1999).

Conveyer belt font by Erik Demaine, Martin Demaine, and Belén Palop, 2008
The form without the belts (lines) is a puzzle to decode, based on a mathematical open problem by Manuel Abellanas first posed in 2001.
From the paper “Conveyer-Belt Alphabet”, in Findings on Elasticity, 2010, to appear.

Origami maze font by Erik Demaine, Martin Demaine, and Jason Ku, 2010
The font can be folded as extruded letters from a rectangle of paper, using an algorithm for folding orthogonal graphs by the same authors.
Based on a theorem from the paper “Folding Any Orthogonal Maze“, to be presented at the 5th International Conference on Origami in Science, Mathematics and Education (OSME 2010), July 2010.
