SPRITE / FLOW FIELD
Flow Field Visualizer
2000 particles steered by a noise-driven vector field. Trails accumulate over time. Tweak scale, speed, and color — or drag your cursor across the field to attract and repel.

ALGORITHM
Each cell stores an angle derived from sin(x)·cos(y) noise.
Particles steer toward the field vector each frame, building luminous trails.
RENDERING
Canvas never fully clears — a 0.008 alpha black fill slowly fades old trails. Each particle is a 1px circle at 5–6% opacity for additive luminance buildup.
INTERACTION
Mouse influence applies within 120px radius. Toggle attract/repel to sculpt the field in real time. Hit Clear to start fresh from black.
