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 350˚ for 30 minutes. Serves 5.

    just a warning that the suggested temp of 350° is Fahrenheit. Don’t bake them at 350°C cause then you’re in for a treat. Believe me, i know.
