William Latham is a British artist and computer scientist who began evolving organic 3D forms with his Mutator software at IBM in the late 1980s. He is professor of computer art at Goldsmiths, University of London.

They said, your Mutator software, can it produce millions of images? And I said, yes, it's got the potential. Even 10 millions.

Latham was drawing forms mutated from each other using pencil and paper. Computers allowed him to make this a rigorous exploration of a much larger space of possible form.
