I've been pondering doing some proof-of-concept videos with dgVoodoo2 using DirectX-based demoscene demos and intros as well as tech demos, but I'm admittidly clueless as to which are the most taxing and/or feature-complete (e.g. uses the widest variety of API functions/methods/whatever). After all, what better way to demonstrate to my skeptical friends just how good dgVoodoo2 is than with something which is difficult to wrap? Any advice would be greatly appreciated!
