Bathsheba Grossman and Vladimir Bulatov make wonderful art objects. They’re math-inspired, but you don’t need a PhD to appreciate their beautiful organic forms. They’re made with a 3D metal-printing technique that produces intricate sculptures impossible with other techniques:

I’ve blogged about Bathsheba before, but I just spent at least an hour poring over these artworks, and following connections from Bulatov’s photos on flickr, so I thought I would share again. Also, Bathsheba has some models in plastic which reduces the cost.
