A regular sine wave defines the base flow direction. Noise then displaces its phase — locally warping regularity into chaos:

angle = sin(x · frequency + noise(x,y) · phaseStrength)

Where displacement is low the sine pattern is clear — parallel ribbons, gentle waves. Where it's high the regularity breaks down into turbulence. Sometimes a second sine at a crossing angle is added, creating interference between two ordered systems, both disrupted by noise.

Key variables: phaseStrength (low = geometric, high = chaotic), frequency (ribbon spacing), phaseSpeed (wave travel speed), trailFade (short vs. long memory), interference (single vs. crossing sines — ~50% of the time).
