Perlin noise is an algorithm written by Ken Perlin to produce sequences that appear both random and organic. The noise() function in p5 produces Perlin noise.
The dots in this example are sized based on noise values. The slider on the left sets the distance between dots. The slider on the right sets an offset in the noise calculation.
