variation of 3BACKS; once diffracted through
3 lasers, now projected by one.
In the traditional viewing situation, we see a new perspective
when we change our position because our eyes cross different
sections of the wavefront. When
a hologram is projected with a moving laser as seen in
this piece, the image appears to move as we remain still.
As was mentioned before, each point on the film is its
own entire image. In this
projection, one laser beam illuminates only one "whole
image" at the time - therefore to slice the laser
throughout the film is to play a short animation of contiguous
viewpoints - as in traditional animation, our brains interpret
the images as movement. The entire mask of
light is in focus, no matter where the screen intersects
