Research on famous sundial design:
The Sundial Bridge (also known as the Sundial Bridge at Turtle Bay) is a cantilever spar cable-stayed bridge for bicycles and pedestrians that spans the Sacramento River in Redding, California, United States and forms a large sundial. It was designed by Santiago Calatrava and completed in 2004 at a cost of US$23,500,000. The bridge has become iconic for Redding.
Huge equatorial sundial in Jaipur, India, built in the eighteenth century. The time is told from the shadow of a fifty-step staircase. Not particularly accurate.
Royal Greenwich Sundial
A remarkable modern sundial is to be found in the grounds of the Royal Greenwich Observatory in Madingley Road, Cambridge. It is a reclining equatorial design. A large ring of stainless steel bearing the hour-lines and numerals reclines at the latitude angle to the horizontal, and a steel bar forms the diameter of the circle. A slender vertically standing rod forms the gnomon; it is carried on a collar on the diameter bar, adjustable to move up and down the bar according to date.
