Holly,

I saw the thread title and thought "Oh man, Holly found a bug", but this is great stuff! I actually have a tool under development now that expands upon wireframe pro's technology to build a dirtying shader. It's a bit stalled right now as I'm completely distracted by making new lighting models for Shaders Plus, but I hope to get back to it after another Shaders Plus update and a Wireframe Pro update currently under construction. You're the first person that saw the same potential I did.
