Wind Chimes
Metal tube chimes hang from a ring and sway as a slow, oscillating breeze passes through. Each tube swings on its own phase and speed offset around two axes, with an occasional exaggerated pulse simulating a soft collision, while a central clapper swings independently in the middle.

• 8 pendulum-hung tubes, each with unique length and swing phase
• Wind gust intensity oscillates slowly via a sine envelope
• Periodic power-curve "bump" pulses simulate soft tube collisions
• Central clapper swings independently between the tubes
• 1200-star backdrop, auto-orbiting camera when idle
