ActionScript 2.0 :: Creating Rain In Flash?

1. One that creates random amounts of single pixeled particles with the same color but random alpha levels.2. Next a Gravity program (like in the Kirupa Tutorial), that will make the particles fall.3. A simple program that as the particles fall makes them all fall at the same varying angle (ex. wind movements to rain).. And lastly and program (simlar to mouse trails) that makes the particles create a fading trail as they fall from whatever they base alpha level is. (ex. a particle that starts as 70% Alpha has a trail of 12 1 pixeled particles that follow it each dereasing by 5% Alpha.)I'd like to see and understand the programming behind this for neone interested in helping me endeavor in this lil experiment. I won't lie to u, it will probably have the same complexities as that of Kirupa's snow. But i think it would be an interesting tutorial to place on his site
