Hope I can describe this.
A kinetic sculpture that's made up of horizontal pieces that
in the wind, (see link) but unlike the example in the link, spin
independent of each other.
Every 3rd piece is a different picture of a person's face
broken up like
lines on a TV screen.
So face one would be on pieces 1, 4, 7,
face two would be spinning pieces 2, 5, 8 etc. There are
faces that are
intermingled with each other so when the they are all lined
you see an indistinct mix of 3 faces.
The effect would occur when the wind is blowing these pieces
and spinning them randomly. Occasionally, enough of the
pieces representing one of the faces would line up sufficiently
to give a glimpse of that face. They'd fade into each
other randomly but from time to time give enough cohesive
information about the image that the brain could get a rough
idea of what the picture it.
It could also be other images broken into 3 parts that would
morph into each other as the wind blew them around such
it might create relaxing and interesting moving images.
