When I was a kid, I used to play with action figures (especially Star Wars, which are still in my attic). Wouldn't it be cool if I could make an action figure of myself to go along with the others so Han Solo and I could fight over Princess Leia? Well, technology has advanced to the point where you can do just that. 3-D printers are now available at the consumer level. What's truly astounding is that the medical field is using 3-D printers to help create 'replacement parts' for people. Lost an ear in a tragic headphone accident? No need to grow one on the back of a rat,

now doctors are working on making new ones.

When I first started watching this video, I thought, wow, I could make a nice statue with this (for my desk). But after watching how intricate the system is, it's only a matter of time before people come up with really useful (as well as crazy) uses for this technology.

A Georgia Tech scientist recently released and iPhone app that would allow users to scan and print models of their own faces.

If you had access to this kind of technology, what would you do with it?
