Construction

One arm declared once and repeated 3x at 120°: a chain of mutually tangent circles (7.6 m head shrinking by x0.92 per step to 0.4 m) along a logarithmic spiral from 13 m to ~70 m path radius over a ~215° clockwise sweep, with five satellite tufts of 3-7 small circles hanging off the outer flank; small flattened circle at the hub.
