What's going on here?

Blender, the open source 3D graphics software, has a lot of cool and useful features for a vfx guy like me. Especially with the new 2.5 release. 3D modeling, rendering, fluid sim., smoke sim. (very cool) and even node-based compositing. From a vfx perspective, however, there is one important tool missing: rotoscoping. So, I have taken it upon myself to write an add-on that will add this missing functionality. After much deliberation I have decided to call it Roto2D and this blog will chronicle its development.
