Minneapolis-based artist and designer John Foster makes sparkling glass objects that look well-suited for the homes of fairies and mermaids. Interested in the geometric structures that govern various natural phenomena, Foster creates iridescent prisms that, when grouped together, cast brilliant reflections in the surrounding space. The artist works in a variety of media, including sculpture, painting, and installation, and seeks to use geometry as a way to change the ways viewers interact with the spaces around them.
