TYPEFACE is an application that creates a custom font using facial recognition via your computer's Webcam. The sophisticated software even allows you to make silly faces at the camera and watch as the typeface adjusts in real time. The project was created using Processing, the open-source programming language.

According to Mary Huang, the project's creator:
The design of typefaces is founded upon principles from the days of metal type, when creating individual fonts was a laborious process and constrained by physical requirements…. Technology gives us opportunities to make type design more spontaneous and personal. In TYPEFACE, letters are constructed from mathematically generated curves controlled by distinct variables that determine such parameters as x-height, slant, bowl curvature, and pen stroke.
