Very cool!  That's just what I was thinking of when I proposed
handwriting-based symbol search for Google Summer of Code.  If you
don't mind my asking, about how long did it take you to write that?
(I don't know if you read the rest of this thread, but we had some
discussion about whether this project would take far more than a
summer to complete, and your answer can certainly help us calibrate
project scope for next year.)

I trained a few symbols on your site and noticed that many of the
symbols are accented letters, just because there are so many of them:
\acute{a}, \acute{b}, \acute{c}, ..., \acute{z}, \hat{a}, \hat{b},
..., \hat{z}, etc.  Maybe you could bias the training requests towards
some of the more obscure or hard-to-name symbols?

Have you already trained the program on the typeset versions of the
symbols, or do you require handwritten input?

Once again, good job!  I hope you manage to get the program trained on
lots of symbols in the near future.  If you can think of some code
enhancements that might be suitable for a GSoC project next summer,
please post them to this list; I'm sure that'll spark some good
