	Is is actually possible with a little work to make a photo similar 
to what you're showing here. Just take a couple of plastic figurines 
and with a little bit of work you can get anything. (Hell, just look 
at the special effects of films from before the CG era!)

	Actually, it uses a lot of 3D features but in a very subtle way. 
Doing small movements not parallel to the image plane is nearly 
impossible in a 2D toon animation package (in practice if not in 
theory) because they require completely redrawing *everything* at 
each frame. Yet those kind of movements add a lot to the feel of the 
animation.

	Then look at this image by the same author:

ember-December1998_ac5Fvs5Feb.jpg

	It doesn't look like a photograph and it doesn't try to. But how 
would you do it without 3D rendering?
