Bathsheba Grossman is an artist that specializes in that geometric zone where art, science and mathematics link together. She produces very unique designs, and many are available for direct purchase over the web. Pictured is the 3 and 3/4 inch long "MG" metal piece, priced at US$325. According to Bathsheba:
I use a lot of technology. 3D printing in metal is the main way that I work, and I also do a lot with subsurface laser damage in glass. This isn't because I love gadgets; it's much more trouble and expense to use new media instead of the more mature techniques that most sculptors enjoy. I do it because the shapes I have in mind aren't moldable, and I want to make a lot of them. Those two constraints, taken together, turn out to be remarkably constraining: ordinary sculpture technology just does not do the job.
