The response to my most recent sculpture, Open Season, was very strong and encouraged me to explore the possibilities of a similar sculpture that did not have a particular theme.  That effort lead me to my creation of Serenity. Similar to Open Season, Serenity has two arms with a simple silhouette  of a bird that rotates in a seemingly random orbit.  In an effort  to accentuate the orbiting bird, I decided to retain the natural shade of the revolving arms so that their movement would blend better  into the background.    The bird is balanced to minimize its sway so that it appears to be floating on winds aloft, seeking for its next thermal. 

Serenity is propelled by a stainless steel constant force spring that is fully wound by placing an index finger next to one of the spokes of the lower right pulley and turning counterclockwise for about 22 turns. Once the drive pulley is released, the sculpture will receive its first 'push' from the spring which lasts less than 2 seconds. The spring will not be needed again until the rear arm slows enough to rotate backwards.  The two arms spin in opposite directions and are completelyindependent from each other.  When the rear arm rotates backwards, a clock-like escape mechanism is tripped which allows the spring to impart another 'push' to the sculpture.  This cycle continues for about 10 hours.
