Title: Play as you like...
Post by: iacob alex on November 11, 2010, 06:04:52 PM

  .....a hammers "game".

       On    www.youtube.com/watch?v=vh2a4a6JPM8   is an up-to-date kinetic (dynamic) sculpture with  a series arrangement of 5 hammers (levers...):if you push by hand,they will move about ten minutes.

       It's a lever concept.

       On    www.youtube.com/watch?v=SAweiAUuus8    (39-41 sec. on movie) ,is the very old (13-th century ) Villard's de Honnecourt proposal for a "gravity wheel" (or "perpetuum mobile"...) with 7 hammers on the rim.

       It's a wheel concept.

       Now,you can play as you like...
