4. Force and Stress
He studied holographic
interferometry. The image
on the right is a two-
exposure hologram of a
plastic dildo. During the first
exposure, a small stone is
left sitting on the top of the
dildo. Between the first and
second exposure, I removed
the stone. The second
exposure is then made
without the stone.
The final hologram shows a
pattern of lines that reveal
the amount and direction of
the force exerted on the
dildo.
5. The Auschwitz Display at
Disneyland
This hologram records a pile of
50 dehydrated chicken heads
stacked on top of a mirror.
