Box of Men is a piece by artist Ken Feingold using animated ventriloquist dolls. The automaton is funny, creepy, and thought-provoking all at once.
From the Ace Gallery Web Site:
Box of Men is a work for display on a large flat-panel screen. The piece
is not pre-recorded. The dialogue is synthesized speech generated in real
time by a computer program that assigns a "character" to each of the
puppets. Their conversation goes on infinitely, as long as the program is
running. The narrative circles around an "unknown" crime. Those accused are anonymous. Those who judge are puppets, controlled by unseen forces, and assuming an uncanny life of their own.
Here is a link to the page featuring Box of Men, complete with transcript of their conversation.
