The Clam Room is where people first entered
the pavilion. Lowell Cross designed the laser deflection
system which used the four colors from a krypton laser.
The highly sensitive mirrors in the system could vibrate
up to rates of 500 cycles per second and were activated
from the sound system in the mirror dome.
The number of technical breakthroughs in
the Pavilion was quite astonishing -- almost every system
we designed was new and untried. But even more significant,
we had created a living responsive environment which each
visitor could explore individually. This was completely
different from the fixed pre-programmed environments of
the other pavilions at Expo 70.
