Kinetic Steam Works, established in 2005, is a Bay Area collective dedicated to steam powered kinetic art, whose mission is to explore and repurpose the artifacts of clockwork modernity. Steam powered machines, simple and intricate, blur the line between art and industry... kinetic masterpieces created during an era of diabolical innovation and gleeful invention.
Sean Orlando's Steampunk Tree House, a 30' tall metal tree with steam instead of sap flowing through it's channels and a wood and metal house nestled within it. A roving veritable steam gardener, in the form of the Kinetic Steam Works will provide regular applications of steam, so that the tree's pipes puff with fluffy white scald. Inside, a veritable treasure trove of gimcracks, trinkets and tiny ephemera tucked into shelves and drawers, as well as surreal paintings adorning the walls.
