Injecting the animation with chaos theroy

My Fish squares are now all individual with the addition of ink splatters, i have about 90 of them now. The idea behind the ink splatters are that although they are all 'connected' within the school, their individuality shines through in their markings much like herd animals like cows... but not sheep... and I'm really not sure about fish.

You'll see examples of the new improved textured fish in the following animations.

I've decided that its a real ball ache animating each of the 90 squares though, so need to find a way of telling after effects to do all the hard work. The first step was to get after effects to generated them (the fish) randomly. The particle emitter effects within after effects are incapable of generating custom particles but this was definitely the route to go.

I found a plug in that would generate custom particles by referencing another composition. The next problem was getting after effects to generate fish with different markings, the default method was just to reference a composition and generate a copy from the emitter, so I told the emitter to reference a random frame from a composition that was built up from a stop frame animation, constructed frame by frame from the 90 or so different squares (and thus markings) I had created. The result was a swarm of squares (the physics need changing to make it behave like a school of fish), each randomly generated and different! I really chuffed with myself, it actually worked.
