Double Random by Ira Greenberg.

Using 2 random() calls the and point() function to create an irregular sawtooth line.


size(200, 200);
background(0);
int totalPts = 300;
float steps = totalPts+1;
stroke(255);
float rand = 0;

for  (int i=1; i< steps; i++){
  point( (width/steps) * i, (height/2) + random(-rand, rand) );
  rand += random(-5, 5);
}
