Our proposed installation demonstrates the principles of solar evolution
by creating a "projection screen" on the interior surface of the observation
tower. The screen consists of a translucent white fiberglass fabric attached
to the mullions by wires, replacing the existing black mesh canopy. Four
identical banks of lights, mounted on the angled sheet rock walls along
the perimeter of the observation deck illuminate their opposing pyramidal
glass skylights. Each bank of lights consists of a main spotlight of 500
watts, with computer controllable color filters and adjustable spot
diameters. These lights can sweep across the skylight, imparting an impression
of motion. The computer will keep the total power at or below 2.5 kw at
all times
The Intellabeam flood lights will be programmed in parallel to the
standard model of stellar evolution (please see the approximate simulations
above for illustration). During the first stage small spots with patterned
irises will sweep across the windows, giving the impression of a rotating
mass of red gases. As time progresses, the Intellabeam systems will project
a stronger yellow center disk as the smaller spots fade away. For
a few minutes, each face of the observation deck glows with a bright yellow
orb, as if enclosing a miniature sun. Then, in Stage 3, the lights turn
bright red and diffuse as the sun explodes. In Stage 4, a bright
white, but smaller image of the sun is centered on the observation deck
windows. Finally, the light fades away.
Each solar cycle will take about five minutes, repeating twelve
times an hour throughout the night. At this high rate, billions of years
of stellar evolution are compressed into a human attention span, so that
people stuck in traffic, strolling in Liberty State Park, or flying over
NYC, can experience an entire sequence without interruption.
However, five hundred watts of lighting per window is, at best,
minimally acceptable for an installation that could be visible 2 miles
away in NYC. Realistically, 500 watts is equivalent to about five 100
watt lights bulbs- which is a bit like peering at a few well lit apartment
windows from across town. Never the less, if testing shows decent visibility,
then some lights may be aimed into the clearstory tower as well.
To complete this commission, Arno Penzias, Nobel Prize in
Physics for co-discovery of the "Big Bang"'s background radiation, has
agreed to act as technical advisor to assure scientific accuracy of the
display.
