As
the participant moves inside the CompuObscura, the projected
image of herself also moves around the Italian plaza.
After a few minutes, she notices that the projected
plaza is starting to fill with large wisps of smoke
(the Lumiere Ghosts) each one of which dimly displays
a shifting collection
of moving images as if they are projected onto the
smoke itself.
If she moves into or through
one of these ghostly screens, she notices that the ghost
screen (and the image it contains) wraps around her
and then dissolves much as “real” smoke
would react in a physical environment. Therefore, moving
her arms up and down eventually causes ghosts to dissipate
or separate, and moving quickly through them causes
them to sweep in behind her.
