I have one of these. It arrived recently; I haven't really tried it yet, but will soon.

Wikipedia: http://en.wikipedia.org/wiki/Camera_lucida -- it notes the basic optics were described in 1611 by Kepler.

You use it to draw/paint? Can you please share something you've done? I'd very curious in seeing anything you've painted with it.
