In the not too distant future, I'll be getting one of those (3D printer, maybe not that specific one). I'm just waiting for a little bit as I'm not quite ready for it's usage, but I will be soon. I can't wait, it'll be so cool.
They had a guy on Colbert not too long ago, that invented a type of these, it'll likely be one like that.
