Fun Algorithmic, Puzzle, and Mathematical Typefaces

posted by Jason Kottke   Oct 27, 2021

The father-son duo of Martin and Erik Demaine make typefaces that are algorithmic, mathematical, or puzzle-like in nature. For instance, here’s their Tetris font, where each letter is made up of the seven possible Tetris pieces:

a typeface where each letter is made from Tetris pieces

Or their newest one, Everything, where each letter can be folded into any other letter:

Everything to everything. This typeface illustrates how to fold any letter into any other letter, or more precisely, how to fold a piece of paper in the shape of any letter into the shape of any other letter. This lets you write one message inside another in a couple of ways. On the one hand, you could present the 6x6 crease patterns whose silhouettes look like one message (first text), and folding them reveals another message (second text). On the other hand, you could present the folded forms (as physical objects) whose silhouettes look like one message (second text), and unfolding them reveals another message (first text).

From a recent-ish profile of the Demaines and their typefaces in the NY Times:

In a 2015 paper, “Fun With Fonts: Algorithmic Typography,” the Demaines explained their motivations: “Scientists use fonts every day to express their research through the written word. But what if the font itself communicated (the spirit of) the research? What if the way text is written, and not just the text itself, engages the reader in the science?”

Inspired by theorems or open problems, the fonts — and the messages they compose — can usually be read only after solving the related puzzle or series of puzzles.

You can check out the rest of their typefaces on their website — they include fonts with infinitely tiling letters, Sudoku puzzle fonts, and a font whose letters are made up of shapes that can be packed into a 6x6 square. So fun!
