As I start to move closer to R&D (i.e. prototyping, or trial and error experimentation), the following stages will be my rough guidelines for what to work on and when:

• Phase 0: Research – I am here. (This is never-ending)
• Phase 1: SceneGraph & Animation – Basic geometry, data structures, occlusion, etc. (Attempt #1)
• Phase 2: Lights & Sound – This is really a two-parter, but I like the sound of the title better. (Plus SceneGraph modifications or Attempt #2)
• Phase 3: Networking & Window System API – Basic network communication and first attempt at a Window System API.
• ...

These will probably change around in the future, but getting myself a direction is a good start.
