Combine it with this http://detexify.kirelabs.org/classify.html and you've got yourself a nifty draw->search tool

Also, if this comment sounds familiar, I left a very similar comment regarding combining the above link with a JS based latex figure output. http://news.ycombinator.com/item?id=815189

Sounds like it could be useful. Of course, it would be infinitely more useful if researchers were using a semantic markup language (perhaps Content MathML) so that equations with the same meaning could be discovered regardless of the actual symbols used.

Not that I'd want to code MathML by hand...
