Trying to make line drawing look like they have volume is as old as the
hills,it is called chiaroscuro in artistic circles.look at the tv
tonight and you will see another form of it.

Most sane people can recognise moving images in 2d can be made to look
like 3d images just like a television does, but for goodness sake that
is as far as it goes.There is a big difference between looking at
images on a screen and looking out the window at the same images.
Human intuition is a great thing,it can enjoy moving 2d images* and
not mix them up with moving objects ,relativity blurs the distinction
and it is extremely unhealthy.

The great human intuitive faculties are designed to pick up on what
the following motions represent,to waste them on cartoon
relativistic/Newtonian conceptions is a waste of a life.

Now,It takes real intuition to know what is going on there !.
