The physical life span of Kinetic Art is evaluated to be ve ry short in comparison with those of stationary works stout and easy for storage such as tableau pictures or bronze sculptures. The results of study on those weak points of Kinetic Art are summarized in next work of this author, in the "Pneumatic Sculpture Series"

Work of Kinetic Art useing Fluid Elements 8 pieces of flute and 2 drums play music by means of combination of medical fluid elements. Musical composition circuit operating on.

It moves like a baton for commanding an orchestra to perform at waltz or rock music. The body consists of rotary pipes serially connected in 3 steps. Each pipe is rotated by a pulse motor via a double flexible shaft and gear. When 3 pulse motors are turned. all pipes make comdex motion because each pipe is bent at each arbitrarily selected position. The pulse motors are driven in accordance with pulsess successively transmitted from a microprocessor.
