Arik Levy used the relatively new process of stereolithography to make this fascinating bowl.

Stereolithography (SLA) is a process of creating "rapid prototypes", allowing one to "print" three-dimensional structures from a digital image. First, a CAD computer model of the object is digitally sliced into very thin layers. Then each digital layer is physically 'drawn' with a laser which fuses together or hardens the chosen material particle by particle. Upon completion, the physical model replicates the CAD computer model to the finest detail.

I like the way it looks in the photo.
