Final answer:
Calder's Crinkly is not motorized; instead, it responds to air currents and is part of Alexander Calder's unique, delicate balance and use of materials in his kinetic mobiles.
Step-by-step explanation:
The statement that Calder's Crinkly is motorized to spin in a circular motion is false. Alexander Calder, renowned for creating the kinetic mobile, crafted mobiles that responded to air currents. His works, including the Big Crinkly, were delicately balanced to move with the subtle flow of air and were not motorized. Calder's mobiles are characterized by the creative use of materials such as painted sheet metal and metal rods, combined with engineering principles for balance, culminating in a unique artistic expression.
