Note: Sometimes the particles start in the four corners....I don't really know what's causing this, but usually if you just refresh it'll work the way it's supposed to.

I've been doing a lot of work playing with flash dynamic kinematics recently (read: I want to feel important by using big words) And a couple of people have wanted to see what I've been up to, so here's on of the prettier things I've done.

*WARNING, PROGRAMMING / PHYSICS CONTENT*
Pretty much I'm dealing with multi particle interactions in a bunch of different ways, this particular model assigns each particle a random mass (the physics definition: resistance to change in current velocity) and related size (the larger the mass, the greater the radius of the particle). Each particle begins with a random x,y velocity, but if they come within 150 pixels of one another, they will create a spring between the two (affecting at a rate of like 0.005, if anyone's interested....just lots of trial and error).

If anyone wants the code for this, feel free to pm me, and I'll try to get back to you
