Font geeks have no clear boundaries, so here's an idea that's weird but oddly compelling: a font containing the signatures of every US president. Yep, you can incorporate a fake Obama signature into your documents no matter how many times he defers visiting Australia.
The font, created by Australian designer Graham Jupp, is free for personal use. We look forward to the Australian prime ministers version. If you'd prefer a more personalised approach (and a more flexible font), convert your own handwriting to a font with YourFonts or FontCapture.
