Originally uploaded by Good Brownie

The Indiana Steam Clock was designed for the Indiana State Museum by horologist Raymond L. Saunders and was inspired by his world famous Gastown Steam Clock in Vancouver, B.C., Canada. This steam clock is made of stainless steel, with brass trim, is 17 feet high, and weighs 1.5 tons. High-pressure steam, that heats the museum, is reduced to 20 PSI for the eight brass whistles. The steam whistles play "Back Home Again (in Indiana)" on the quarter hour. A model of the earth, rotating at 3RPM, is illuminated by a miniature 'sun' lamp.
