RepRap ftw!

I've been reading up on the RepRap, which is basically a 3D printer, i.e. a printer that can create physical objects, not just ink-on-paper.  I really want to build one of my own, but jumping in cold will be a challenge.  For now, I'm signed up on the reprap-michigan google group to follow the progress of local reprap users, and hopefully be able to attend a gathering of these fine folk to learn more.
