Inspired by his childhood adventures in Yellowstone National Park, Daniel MacDonald began growing mineral sculptures in his living room. (He calls the space his “Growth Chamber.”) Each structure is formed over the course of a week by running salt water over a bare skeleton of fabric and plastic, causing unique systems of salt crystals to grow, and then lighted from within to create a lighting fixture that is equal parts art object and science experiment. He calls it shio, and he wants to make one of these otherworldly lamps for you.
