These vintage sculptures, with their colorless geometric shape, are unique in the Simpson oeuvre. Yet they are also classic Josh, offering more and more intriguing detail the longer you look. They're also somewhat evocative of ice, icebergs, and ice formations!
Originally intended as optics experiments, they were created when Josh used his milling machine to cut patterns in brass and aluminum plates, and then used these plates to shape the molten glass. On some pieces he added carved geometric lines, and into many of them he blew a perfect bubble that would act as a lens to bend and magnify the interior patterns visible through a polished façade.
