The novice level classes focus on modeling, animation, and materials; but I am planning on introducing BGE on the last day. An advanced level class would spend a lot more time on BGE, fluid dynamics, composite nodes, etc.

I played around with the BGE dome camera a bit – made a little game that I played in my planetarium until I got sick! It was awesome.

Ron Proctor, don't forget to talk about the BGE and its Dome possibilities :) :

For planetariums, you may wanna try the code currently available in the branch 'ge_dome'.
There is an horizontal tilt option there that makes easy for planetariums to adjust the camera to its rotation.

Feel free to write me if you have any questions.
