Hey, this is really cool, and a great visual language for regular expressions! Must have been fun to build. I found a couple of bugs: it doesn't seem to handle `?>` and inline modifiers (http://www.regular-expressions.info/modifiers.html http://www.regular-expressions.info/modifiers.html), and with a couple of expressions it simply gave me a server error with no further information.
