Hand tracking v3 — Restore
Scatter them all you like — each ball keeps a spring to its remembered spot, so the pattern the hand ploughs apart quietly re-knits itself behind it.
This field of neon balls behaves like stretched fabric: push through it with the tracked hand and the pattern deforms around the fingers, then quietly re-knits as every ball glides back to its remembered spot.
Each ball stores the position it spawned at, and every frame a restoring force proportional to its displacement — clamped to a gentle ceiling — drags it home while the hand's static colliders shoulder it aside. Hard collision out, soft spring back is the whole piece; with no trail fade this time, the image stays crisp.
