Bob Terwilliger's jacuzzi, Coconut Grove (Florida, USA)

The new dial (April 1997)

Sundials can be laid out on any surface, as Bob Terwilliger demonstrated. He built the trigon, a smart laser pointing device, to simulate the sun's position and trace hour and date lines. His 'arbitrary' object was an abandoned jacuzzi, which withstood the harsh Florida climate for another three years.
