Ring Density 75

Concentric circle count

Orbital Shift Speed 0.5

Phase drift speed

64 chars low

Analytical Equation

I(x, y) = \cos(k_1 \|\mathbf{r} - \mathbf{c}_1\|) + \cos(k_2 \|\mathbf{r} - \mathbf{c}_2(t)\|)

Compact Formula

fringe = arc(c1, r) + arc(c2(t), r), beat_frequency = |k1 - k2|

Renderer Logic

for (let r = 5; r < maxR; r += step) {
  ctx.arc(c1x, c1y, r, 0, Math.PI * 2);
  ctx.arc(c2x, c2y, r, 0, Math.PI * 2);
}
