Butterflies

p = ecos(θ) – 2 cos(4 θ) + sin5(θ/12)

or in ActionScript:

var r:Number = Math.exp(Math.cos(i)) – 2 * Math.cos(i * 4) + Math.pow(Math.sin(i / 12), 5);

r = radius, θ = angle. Figure out the x and y from there.

Randomly scale, position, rotate. Coat with bevel and dropshadow. Bake at 350Ëš for 30 minutes. Serves 5.

Another file off the old hard drive. This one actually has nothing to do with the Particle Storm one, but obviously I was thinking along the same lines that day.

Particle Storm 3

Have this insane goal to try to post something every day. I doubt I’ll keep up, but I’ll try. Anyway, digging around my hard disk I found a revision of a piece I called “Particle Storm” that I posted on BIT-101 a while back.

Ran it a couple of times and came up with this:
