A brilliant idea! Would love to see a blog post overviewing how it works.

Maybe it just uses a CAPTCHA solver to get a list of likely characters?

Well hopefully the author of this will give a real summary, but I had a quick squiz at the code at its nothing like a CAPTCHA solver.

Basically its a nearest neighbour classifier based on turning the actual stroke data in sets of equally spaced points after being centred and scaled. The direction between points is recoded as compass directions (so sequences of N,E,NE). These strings are matched against the training data to find the closest matches.
