Prime node Non‑prime node Recursive attractor

Spiral Parameters (r = a·e^(bθ))

a (scale) b (growth)

θ step (rad)

Max points

Point size

Rotation (deg)

Coloring Rules

Prime rule index n is prime round(r) is prime

Attractor modulus M

Attractor anchor A

Attractor check on index n round(r) round(θ·100)

If M>0 then a point is an attractor when value ≡ A (mod M). Otherwise, every k-th point can be used with M=k and A=0.

Play

Tip: try b=0.18, θ step=0.06, M=1000, A=137 for a Domain‑137 motif. For a denser icon, increase max points and reduce point size.
