Inspired by a pattern on the back of a gardener's flyer advert thing, SJ and I decided to make a trippy moving thing.
var segments = 40,
rotStep = 0,
angle = Math.PI * 2 / segments,
radStep = 100;
function setup() {
createCanvas(600, 600).parent('canvas-container');
}
function draw() {
var i = segments,
radius = Math.sin(radStep) * 10 + 130,
diameter = radius * 2;
translate(width/2, height/2);
background(0);
rotate(rotStep);
rotStep -= 0.002;
radStep += 0.007;
fill(0, 0);
stroke(255);
while (i--) {
ellipse(radius, 0, diameter, diameter);
rotate(angle);
}
}
