A designer called Mary Huang has concocted a rather nifty bit of software which allows anyone to create a font unique to them, using the proportions of their face.
It's called Typeface, and uses a webcam and some facial analysis software to determine the distances between different parts of your beautiful visage. It then uses those distances to generate ratios which it applies to font, meaning that your typeface is pretty much unique to you.
Huang says: "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. Most digital type design follows those same conventions, but technology gives us opportunities to make type design more spontaneous and personal".
There's no download for the app just yet, but in a blog post, Huang says it should be ready within a few weeks. Bookmark the site and check back then.
