Just curious, but would there be any? I mean really old fashioned ones.... like this: http://home.earthlink.net/~dcrehr/firsttw.html Which was the first ever and was made in the 1800s.
Now, I'm not trying to say every Tom, Dick and H'rold should have one, cause they'd be stupid expensive, but limited to means and so on.
And if there aren't currently, would it be completly not cool for a plot to be done where some Technicians and some Printers got together and invented one? *G* Once again, it'd be way to crazy expensive to be mass-produced or anything... a very luxury item that would only be owned by the most wealthy or perhaps a Hall would own a few collectively or something.
Just wondering.
