I imagined the concept of prana—the vital life force—traveling up along the human spine. I wanted to capture the feeling of an ascending, internal energy that breathes, twists, and pulses in complete harmony with sound.
The technical workflow starts with a simple tube geometry. I distorted this base shape using noise operators to mimic the organic, slightly irregular curvature of a spinal cord. Instead of rendering it as a solid object, I fed this structure into a GPU particle system. This allowed me to break the rigid geometry down into a fluid, upward-moving stream of light.
To make this energy truly alive, I integrated targeted audio analysis. By passing the sound through filters and envelopes, I extracted the core rhythmic data and mapped it directly to the particle system's turbulence and structural forces. Because of this, the particles surge upward and scatter dynamically, reacting instantly to the intensity and build-up of the track.
That ethereal, ghost-like glow was achieved in the post-processing stage. I combined a feedback loop with a luma blur to give the movement a soft, lingering persistence. This final touch was crucial; it made the visual feel less like a digital simulation and more like a pure, radiating column of consciousness and energy.
