The Steampunk Treehouse is a large steel tree and treehouse designed in the "Steampunk" style. Visitors are allowed into the bulkhead door at the base of the trunk and then must climb the inner structure to get into the treehouse at the top. It debuted at the Burning Man festival in Nevada, US, in August 2007. Lighting is predominantly hi-flux LEDs in custom designed arrangements.
