Regulazy is a visual Regular Expression builder - looks like Roy has been busy :)
"Regulazy is an attempt to build a small "Expert System" for creating .NET Regular Expressions.
It lets the user create an expression based on a real life example of text they would like to parse.
As the user interacts with Regulazy using the mouse, Regulazy
offers the user possible expressions that would fit the currently
selected text. As the user selects "rules" to apply on various parts of
the text,
a regular expression is built automatically in the lower application pane."
Looks very cool to me!
