## Ada Font |
## by Ada Bienkowska, Erik Demaine, and Martin Demaine, 2018 |

**Two shapes.** At age 3, Ada wrote both letters of her name (A and D) using two simpler symbols: a U shape and a line. Together we designed a complete typeface where each letter, digit, and punctuation is written with exactly these two symbols, each used exactly once. Every U shape has exactly the same proportions; the shapes are just rotated and/or scaled.

**Puzzle fonts.** To obscure the letters and turn text into a puzzle, you can **rotate** the U shapes by 180° and/or rotate the lines by 90° (using the checkboxes in the top right). You can also **animate** these rotations for a surprising animation font.
