Today’s Google doodle honors the 113th birthday of modern sculptor Alexander Calder (1898-1976), who was famous for his hanging mobiles and wire sculptures of famous people.
Unlike the Calder mobiles in museums, however, users can interact with this one by tilting their laptops or moving their cursors over the HTML5 doodle to make it sway from side to side. Procrastinate for a few minutes and play around with it.
