I know that there is a heatwave mesh out there and iv'e used it alot but there is something missing. And another thing missing out there is a good Pied Piper so just a day ago I happened uppon some great sourcematerial at newsarama.
So i'm putting this out there for anyone who's interested.

Oh and the Flash Rouges rule...

I'm pretty sure a Pied Piper was in the works but never released.

Yes he's (Pied Piper) been scoped and the skinning is mostly done. But haven't had time to explore a better set of keyframes for him. But he is in the works as well as Golden Glider for all you Flash fans.

I thought the Piper in the works was the classic version.  Is there a new version available/being worked on, as well?

Well my original plan was to do both. The classic version was scoped by flash. I was going to also adapt that scope to the modern version. I've also done Plunder (yet to be released)
