This proposal, created for the City of Bellingham, repurposed a 30ft diameter spherical steel digester tank known as the “Acid Ball” into a public sculpture for our new waterfront district.  The re-appropriation would transform the tank including all of it’s riveted seams into the world’s largest globe sun dial.  The shadow cast on a globe by the sun mimics exactly the shadow on the Earth in real time.  The continents of the proposed sculpture show where on the planet is currently experiencing sunrise and sunset.  The shadow casting gnomons along it’s equator mark the solar time here in Bellingham, WA USA.  This proposal was an awesome opportunity to work with two sun dial experts (gnomoinologists) and learn the kinetic intricacies including the math, science, history and art of working with the sun in sculpture.
