This mobile is made of 39 separate beams connected to each other by loops. The lowest beam is only 10 mm (0.39 in) long and has a radius of only 0.5 mm (0.02 in). As the mobile goes up, the radius from one beam to the next increases by 0.04 mm (0.002 in) and the length of each beam increases by a factor of 1.12 until it reaches the top beam measuring 550 mm (21.5 in) in length and 1.87 mm (0.07 in) in radius.
