Customizable clusters

It is cool and very simple. I created a function named drawCircle() to create a single cluster. A cluster appears on the position of the mouse.

function drawCircle(h, s, b) {

for (var i = 0; i < windowHeight; i += 5) {

rotate(frameCount *0.01);

stroke(h, s, b);

point(i, 0);

}

}

Try it yourself.
