Kinetic sculpture. It's a term made perhaps most famous by Alexander Calder back in the day for his mobiles, but Peter Antor's own interpretation of the concept ties into a broader aesthetic that involves the vastness of buildings, the cavernous insides of structures constructed by human beings, and perhaps not a few science fiction space vessels.
Peter takes great care to carefully articulate mechanisms which allow his art to move and transform into different states. For example, a fabricated lever allows a portal to be opened, from which a shining city pin can be removed, or inserted. The delight is as real as the immensely tactile quality of his work. The fact that every piece of his sculptures and jewelry was fashioned by his own two hands makes each creation a treasure.
