the pure metal onesreally*have my interest; I'm waiting for them
to mature as well, although I'd be happy with the little one
they sell that looks like a toaster oven.. But I can wait. *I'm
learning what I can about it here and there, so that I'm ready.
We're very close to being able to move your phone/tablet around
the room as it converts into voxels, then having it stream to a
3D printer printing out a 3D map of the area that's, say, Lego
size. We have all the parts to do it - I'm just waiting for
someone to come up with the idea that has access to the tools
needed. *Can't wait :D
