I've got a new technical rigging demo up for this thesis project thingy. Check it out here.
It's the most advanced and flexible rig I've ever created before and I've been learning a lot about mel scripting in the process. I think I'm going to create a custom window with all my scripts in it because sometimes there're just useful utility scripts that get made for a project and not really saved.
For example I wrote a script that took the selected control object and colored it. Red for RIGHT and Blue for LEFT. Very simple, very useful in a character rig and I wouldn't want it to get lost in the code ... so Jason Manak's MEL Scripting Bible ... a project in planning.
