This is actually a street performer in Los Angeles, the mysterious Mirror Man. I think this is a fantastic idea. I think as a static sculpture it would be an arresting image and bring up metaphysical contemplation, but the added layer of it being a live performer really brings it up another level. Would love to experience this in person.
Unfortunately I can’t find any more info about this artist/performer, but you can check out a lot more images of this scene at SiLver sKY’s flickr photostream where I found this.
