Showing the state machine is cool, but I'd recommend adding more room for test cases, ala regexpal.com.
A set of fail strings would be useful, it's something no-one else does but it vital for a good user experience.

How would you recommend generating fail string? The space of failing strings is really large. From my discussions with users, they usually have a specific failed string and they want to see why it doesn't work.
