I've been looking for tools that would help me do this. Are there any interesting datasets that you have converted to regexes with this?
Zipcodes would be something I'd like to see available as regexes.

(Edit: If you want the full ZIP+4 where it's given, you can add (\-\d{4})? as a term in the regex, and you can validate them the same way. USPS also offers an API for validating address information; it's been some years since I used it, and I recall it being somewhat recondite in the fashion of most .gov APIs, but it's there and it works.)
Edit again: OK, the site loaded. It looks like a tool for generating regexes via machine learning techniques to match highly complex targets. From a purely technical perspective, that sounds really neat -- but from a maintainability perspective, it sounds like even more of a nightmare than complex regexes usually are.
I like that!
