(2 OF 2):
At the base of the hemisphere, and
just above water line, is a fog manifold providing an envelope
of fog which rides up on the downward moving sheet of water. The
hemisphere is penetrated from the inside with end-emission optic
fibres which provide a spot of light for each city, or metropolitan
area, of 200,000 people or more, in the northern hemisphere. The
undulating flow of water over each spot of light causes it to
appear to vary in intensity. The optic fiber illuminator together
with all optic fibre cables, color changer and various other controls
are installed within the hemisphere. The balance of equipment
is located remotely, less than 100 ft. away.
The basic idea was to provide a sense
of how the northern hemisphere might look at night viewed from
space through swirling cloud cover.
The fountain succeeded beyond everyone's
dreams. People came from all over just to look at it. Some times
they came by the bus load. They even took pictures of each other
standing next to it. The casino owners noted that while the people
came to look at the fountain they were not staying to gamble;
and replaced the fountain with slot machines.
