**Random Gaussian.**

This sketch draws ellipses with x and y locations tied to a gaussian distribution of random numbers.

void setup() { size(640, 360); background(0); } void draw() { // Get a gaussian random number w/ mean of 0 and standard deviation of 1.0 float val = randomGaussian(); float sd = 60; // Define a standard deviation float mean = width/2; // Define a mean value (middle of the screen along the x-axis) float x = ( val * sd ) + mean; // Scale the gaussian random number by standard deviation and mean noStroke(); fill(255, 10); noStroke(); ellipse(x, height/2, 32, 32); // Draw an ellipse at our "normal" random location }
