Ran across this pic today - thought it worth sharing with those of us
that remember one of the early exploratirum light exhibits that
featured chromed christmas tree balls, where the light gets trapped
below the visual equator of the bulbs and goes completely black for
the viewer. Wasn't it one of Joe Ansel's?
The designers claim they got their inspiration from elsewhere :)
