a port of the Processing Visualization Language


A millisecond is 1/1000 of a second. Processing keeps track of the number of milliseconds a program has run. By modifying this number with the modulo(%) operator, different patterns in time are created.

float scale;

void setup()


  size(200, 200);


  scale = width/10;


void draw()


  for(int i=0; i<scale; i++) {

    colorMode(RGB, (i+1) * scale * 10);

    fill(millis()%((i+1) * scale * 10) );

    rect(i*scale, 0, scale, height);
