Everyone who came to the instructor’s retreat was asked to bring an object that would fit into a 4 x 4 x 4 inch square. The first night these were placed into this grid along with a tag saying who had made each item. After that, anyone was welcome to alter or add to someone else’s object. People brought tiny sculptures, found objects, inscrutable constructions, and visual ideas.
Every day it changes as something gets a new coat of paint, another item sprouts a little stand, a tiny paper figure appears between two sheets of glass, or a blank book acquires some content. You and your friends could do this, too.
