This piece rows of reflective mirrors that interact with a user’s movement when the person moves close to them.
I particularly liked the different moods it creates when you interact with the piece. It almost feels as if an entity is following and watching you as you walk past the mirrors. Yet, when you stand in front of the piece and play with it, the mirrors “play” back to you in response.

It would be even better if the mirrors could move around in addition to changing their orientation. This would be able to bring out the experience more so than non-moving mirrors (imagine the mirrors following you when you walk away from them!).
