Noise Field

/*

  Perlin Noise mathematically generates an infinite field of random numbers between 0 and 1

  They are somewhat close to each other in value, that gives a natural cohesion to them

*/

float noiseScale = 0.02; //change scale to get different outputs

size( 500, 500);

for (int x =0; x<width; x++) {

  for (int y = 0; y<height; y++) {

    float n = noise(x*noiseScale, y*noiseScale);

    stroke(n*255); // n is between 0 and 1
