The clouds theme produces an animation based on perlean noise. Both the foreground (cloud) and background (sky)
color properties can be bound to color Picker controls.
The clouds are painted transparently over the background color, so this module can also
be used by the Displace and Matte modules to interesting effect.
This module is a refactoring of the most excellent
ActionScript 3 Clouds Tutorial
by Dan Gries and Barbara Kaskosz. Many creative and easy to follow examples of heavy math coding in ActionScript are
available on their Flash and Math blog.
