A loose visual analogy to string theory: each glowing filament is a standing wave, echoing how a vibrating string's resonant modes (harmonics) are theorized to give rise to distinct particle properties. Each string's shape is computed analytically each frame by summing sine-wave terms along its length with a fixed harmonic node count and an envelope that pins the endpoints, then rebuilding a TubeGeometry from the resulting Catmull-Rom curve every frame (no physical integration, purely function-of-time). Roughly a third of the strings add a second out-of-phase oscillation for a helical/Lissajous 3D twist instead of flat 2D vibration.
