As we are well into the new century, there is little left in our lives that has not been touched and transformed by the digital revolution of the late 20th century.

Nevertheless, the basic work of transforming an idea into clay remains as it has been for centuries. Pittsburgh spatial artist and designer Brian Peters is changing all that. Using 3-D printing technology, Peters creates ceramic blocks and tiles for architectural installations and for smaller-scale art pieces, starting not with a slug of clay but with a computer.
