dark pattern of dots with white ridges curving up in the center, and dim dark bands running horozontally
The zeros of 10,000 different L-functions. The curved white regions (called “sand dunes” by Michael Rubinstein, who discovered them) come from universal properties of the zeros of L-functions. The darker horizontal bands are the shadows of zeros of the Riemann zeta function.

The Z-function of the first rank 4 elliptic curve.
The “fangs” are due to the influence of the zeros of the Riemann zeta function.

orange square with green-yellow lines running horizontally, vertically, and diagonally
The triple correlation of the zeros of the Riemann zeta function.
The stripes are due to the influence of the first few zeros of the Riemann zeta function on the later zeros.
