CSS: Movement without javascript??

This is just a nice example of the CSS power. Actually, and the most amazing of this example is the use of CSS 1!!!, just that, ..although in one example there is an attribute used at CSS 2.

It works in all major browsers but in IE6, ...you already know how complicated was that version..

The creator of these examples is Román Cortés:

Paper Bird.
Coke Rotating.

At any case, and although the effects are really cooool, what has happened with 3D Programming?? hmmmmm, do u know js3d??, it lets you achive things like this.
