Digital sculpting

I have done some digital sculpting as it pertains to computer graphics work. In the early days one had to do box modelling which was like picking at hexagonal mesh or wire--very different from real life sculpting.

But programs advanced so one could use a pen or mouse as if it were pushing a soft surface on the screen.
It isnt like real sculpting either but has some advantages over box modelling.

I have mostly used it for creating texture maps(the surface detail for cg characters) and for experimenting with extreme facial expressions. But I would prefer transferring that to real life sculpting rather than trying to get prints made (taking the digital sculpture and having it printed out as a real object).
