I didn't know I could use strokes in emacs! I'll have to check it out...

I found some public domain neural network python code :) which I have
used
successfully to recognize digitized strokes. You can grab the gesture
library here <http://sourceforge.net/projects/jestur>. It very much
alpha code at 
the moment. It seems the key to success is the way in which strokes are 
digitised. I'm not sure I've found it yet...
