3-D field guides in our future?

I've been wondering what the future holds for the field guide. The thing I think that's missing from traditional field guides are 3-D images. So I began to visualize what an on-line 3-D field guide would look like. Here are some samples currently available:
Aves 3-D:  A three dimensional database of avian skeletal morphology: http://aves3d.org/

Zoological Museum Amsterdam Type specimens in 3D

Well, it's a start!
