I like this piece because it redefines what a mirror can be made of. We can’t think of mirrors in any other way than just the shiny smooth glass surfaces we are used to. This work is successful in that it provides a working version of a mirror in a medium that we wouldn’t think could be used to make one. This mirror is made of pinball-like balls that are moved by motors, directed by a camera, to produce the image that the camera sees. I’m not really sure how this could be taken to a new direction, other than finding other unusual ways to make a functioning mirror.
