We have been contacted by a school in Singapore, who would like to install
a large playground sundial - BUT ideally having nothing above
airport. The building was L-shaped, one leg a bit higher than the other. A
wire across the inner angle from one leg to the other leg was possible and
because the height difference was the angle 1.5°. The hour lines were on
the parking lot below. The shadow was visible on the parking lot. The
altitude of the arms above the ground. With this in mind, perhaps a
fan-out of marks and associated hour lines for various heights to
account for children of different ages. This could be an attractive
display on the ground. Maybe different colors for different gnomon
heights. As a
Douglas,
The sundial can be reduced to a mark on the playground where a person has to
take place, an indication for the direction the person has to strech out his
arms horizontally and the corresponding hour-lines.
