Sundial of the month February

Gigantic sundial

Orlando USA

Worldwide, there are a number of very large sundials.
Here we show one near Orlando, Florida, USA, which is easily seen on GoogleEarth.

In 1990, the Disney Team Building was built here.
Between two elongated four-storied buildings is a nearly cylindrical structure, open on top. It towers far above the office buildings.

On the outside of this cylinder is a line pattern that seems to be part of a sundial.
But that is not the case. It is only a reflection of the real sundial which is inside the building.

The building was designed by Japanese architect Arata Isozaki; the sundial by the American Ross McCluney.

The next photograph shows the author, dwarfed by its size, admiring this remarkable sundial.

The line pattern consists of hour lines and date lines.
A ball forms the nodus on the large counterweighted gnomon. Its shadow is the readout point.
The building is not exactly cylindrical, and therefore the sundial pattern was plotted point by point using a laser.
