I just think this is a cool feature. MS does some really cool things with handwriting recognition.

An additional flourish on the signature, to make it more distinct and personal. I've been pretty lost for the past 5 pages, but I do like this signature metaphor. We sign things nearly as often as people in the 20th Century did, but we've gotten a lot sloppier thanks to shoddy e-signing on credit card machines. Still, I can look at my signatures and identify them as mine, even though there's no master-signature for me to compare them against. There's a scene in the novel The Talented Mr. Ripley where the bank investigating the disappearance of Tom Ripley does a signature analysis of his recent checks, but they underestimate how long Dickey's been impersonating Tom, so that they're comparing those checks against earlier forgeries.

This looks like something I could integrate into my workflow.
