File Mary Huang's Typeface, a piece of software that analyzes your face in real time to create a custom font, in the "projects preceded by their puns" category. But unlike some things with that designation, Typeface is surprisingly functional.
Stick your face in front of a webcam and Typeface will analyze it live to generate a custom font, stretching and shaping the letters dynamically as you make different faces and change the proportions between your features.
If you want to immortalize the space between your eyes as the space between your "i"s, you'll have to get in contact with Huang yourself; Typeface is currently only a piece in her design portfolio. [Rhyme and Reason Creative via DesignBoom]
