Spiral Moiré

It started by creating a Low-discrepancy, or quasi-random sequence filling a circular area along a spiral.
Using a polar formula
x=\sqrt{\theta} \cdot cos(f \cdot \sqrt{\theta}), y=\sqrt{\theta} \cdot sin(f \cdot \sqrt{\theta})
gives a nice even-looking result:

When both the number of pixels and the rotations around the origin are increased, things start to get artistic. These are the results of choosing number of pixels to 75000, and value of ‘factor’ was 11.1:
