Bathsheba Grossman is an insanely cool artist. As she describes herself on her website, she is:

I’m a digital sculptor, combining prototyping technology with metal crafting skills to create abstract geometries in space.

My work explores order in 3D: the tension between inside and outside, the point at zero and the point at infinite distance, how the axes can be alike and different. I got interested in these ideas as a mathematics student, wanting to cross over from formal abstractions into working with physical shapes, and sculpture gave me the way.

She designs her stuff on a computer, sometimes writing programs to help figure out the weird dimensionality of the objects, then prints it on a 3D printer. That trippy thing pictured above is called “Moon Pi” and is actually a puzzle. If you really want to fry your noodle, check out her 120-cell.

She’s like Escher, if Escher had sculpted. (Actually, the idea of Escher having access to computer-assisted design and 3D printing is almost scary.)
