Fontifier - Your own handwriting on your computer

This seems like a really fun/clever idea! However, I can’t help being paranoid about making my signature so easy to forge….
“Fontifier lets you use your own handwriting for the text you write on your computer.
It turns a scanned sample of your handwriting into a handwriting font that you can use
in your word processor or graphics program, just like regular fonts such as Helvetica.”
