I'd like to see a different approach to teaching some things possibly.
For instance, talking about a workflow for making 3D models, talking about techniques for specific programs such as Maya compared to 3DSMax, the approaches needed to be taken for mechanical models/rigging versus character modelling and rigging, etc.
That and how to write different kinds of shaders for different art styles and visual effects would be nice! Making abstract animated visuals for 3D spaces ala Rez or DDR SuperNOVA would also be a welcome addition.
