This object came to me as a brass kick plate on an old door. It is possible this piece was some other brass object before it was recycled into the kick plate. Now it is an activity sensor disguised as a mobile that hangs in my living room.
It hangs from our ceiling and the top two “s” shaped plates are not attached. They just balance on a recessed point. They have lots of movement.
My children and their friends seem to manage to send it crashing to the floor more often than they think I am aware of.
Regular inspection of this object revels when it has been knocked about the living room. Often the clues are subtle irregularities in the wires or balance. I sometimes am happy the boys are so good at mobile repair and balancing. Other times I just imagine what kind of misbehavior has been taking place in my living room!
