My automton Training for Christmas featuring Santa Claus doing exercises, is on display at The Charles River Museum of Industry in Waltham, Massachusetts, USA. The exhibit shows automata through time and has a section featuring automata that visitors can operate. My piece is on display among a number of others by automata artists you may know, and some you may not know, but should.
The museum has lots of other things of interest to the mechanically-minded: engines, machine tools, pocket watches, bicycles, and a car from 1907!
