Boulder-based artist Mark Castator (FB) creates planets and moons from hundreds of small scrap metal pieces called “droppings” leftover form other sculpting projects. He’s created dozens of these incredible spheroid objects for this series entitled Moons of Jupiter. Most striking to me is that despite being welded steel they appear extremely delicate, as if a strong wind would cause them to collapse. Castator just finished a show at Walker Fine Art in Denver and has work at Winterowd Fine Art in Santa Fe. Photos courtesy Josh Raymond Photography. Thanks Mark for sharing your work with Colossal!
