Perpetual Motion Norman Rockwell 1920
 Cover of the October 1920 issue of Popular Science magazine, painted by American illustrator Norman Rockwell. It depicts an inventor working on a perpetual motion machine. The device shown is a "mass leverage" device, where the spherical weights on the right have more leverage than those on the left, supposedly creating a perpetual rotation, but there are a greater number of weights to the left, balancing the device.
