Treat each ball and its vertical cord as a rigid pendulum rotating around its fixed attachment point under the top bar. Keep the stand, top bar, side supports, and base stationary. From the centered starting pose, the rightmost pendulum swings outward to the right first in a smooth eased arc, reaches about 22 degrees from vertical, then rotates back to its vertical angle in the provided SVG. As it returns, transfer the motion to the leftmost pendulum: it swings outward to the left, reaches about 22 degrees from vertical, then returns to vertical. The two middle pendulums remain nearly vertical, each making two tiny reactive tilts per cycle in the direction of the active end ball—one just after the rightmost pendulum reaches its widest point and one just after the leftmost pendulum reaches its widest point—and rotating back to vertical after each tilt. Preserve the existing layering so the fixed support visually stays in front if an end ball overlaps it, and repeat the right-end-then-left-end motion for 10 total cycles.
