Perlin Particle Storm - A Turbulent Display of Thousands of Particles in AS3 Flash

Enjoy a spectacular particle storm! In this experiment
we use a bitmap filled with Perlin noise to create
an acceleration field. The field controls the motion of thousands
of particles creating a turbulent, dramatic effect.
We use filters and color transforms to obtain the effect
of fading trails behind the churning particles.
