Domain-warping noise with noise is the core organic visual move — turbulent, liquid, marbled

The organic style — smoke, current, cells, growth — is built from coherent noise in motion. The central technique is domain warping: feeding a noise-field into modulation-warp so that the lookup coordinates of one noise layer are displaced by another. This produces turbulent, liquid, marbled results that are harder to describe than to build and that closely resemble natural phenomena because natural phenomena are often self-similar at multiple scales. The foundation is a noise-field using FBM for natural multi-scale detail, set in motion with a flow-field and/or modulation-warp. Adding noise-drift so parameters wander slowly prevents mechanical looping, and feedback-trail with blur-soften contributes smoke/tendril persistence and soft edges.

Examples

Hydra: noise(3,0.1).modulate(noise(2,0.15),0.3).out() — noise modulated by noise gives the liquid marbled core of an organic patch. Add .add(src(o0).scale(0.999).mult(solid(0,0,0,0.02))) for smoke trails.

Assessment

Describe the build order for an organic visual starting from a blank canvas: name the four technique steps (what concept each introduces and what it contributes to the look). Then explain why domain-warping noise with noise specifically produces organic rather than geometric results.
