Fontifier is a service that creates a TrueType font from your handwriting sample. Print out their template, fill it out, scan it back in, pay a little money, and you have your font.
An interesting tech note from the site:
The Fontifier Web site is based on the Common Lisp Hypermedia Server, a Web server designed for advanced applications in AI and research, and developed at the Massachusetts Institute of Technology Artificial Intelligence Laboratory.
I remember seeing a service exactly like this in PC Magazine about 10 years ago. But I use proper typefaces so that what I write is readable, not the other way around.
I did this when it first came out and was still free… The kerning and stuff is horrible of course, but it was still pretty cool. I wrote the letters directly in photoshop with my Wacom Tablet.
