I know this thread is about making 3d out of stuff in game... but taking that the other way around is sort of neat too. Several years ago I got imodeller and also got a free version of dsculptor off magazine cd... check it out... it's 3d scanning with nothing but a digital camera and a blown up grid.

I don't have the model on me, but maybe I can find it on an old cd somewhere... I blew the grid up and put it on masonite sheets, and actually got a 3d model of my sister and brother-in-law a few years back. I was going to do it for cars and things too until I read about how many times Ford has sent cease and desist letters out to 3d artists...
In theory, you could make a model of yourself, and have it printed in a glass statue using something like the links two posts up...
At one point in time, I was thinking about making that in to a career, doing it at fairs and stuff, but it would not work well since it requires lots of angles with the camera, and most people tend to fidget a little. You could theoretically build a rig of multple cameras, but that could get pricey fast.
Imagine doing something like this sort of stuff and using the resulting 3d file as an avatar... of course, 3d scans would suck as avatars since they are not usually animated without a LOT of work, but in the future, this sort of stuff will be possible...
