I modified the slow dancing sprial, that I've written in processing yesterday, a bit. I added a blurrines factor to the position of the dots that sit on a spiral. Now the spiral dissolves to complete chaos from time to time only to restructure itself short thereafter. The blurriness is also controlled by a noise function based on the frameCount but with a different time scaling than the rotation values. I've set the scaling factors to random float numbers that share little to no common factors to prevent the movements from becoming to periodic.
