I love fonts and the  iFontMaker is the perfect tool to create fonts. There is a Windows version also of iFontMaker.

iFontMaker is the first font editor exclusive for iPad. With iPad touch interface, your 100% original hand typeface can be done in 5 minutes. You can email the typography or convert it into a TTF file available in all applications such as Adobe CreativeSuite, Microsoft Office for Mac  and Windows, and also in your web site as a web font!

iFontMaker has a superb free-hand editor. It allows you to be able to make your font in 5 minutes.
