Look at Kyoko Date, the virtual Japanese pop icon. Lots of polygons and lots of 3d artists made videos, and magazine spreads starting in 1996. This is just the latest iteration.
Kyonko Date still looked better. I don't have a valid URL for info on this, but if you search for "Kyoko Date" about a million fan pages will come up.
