Image Factory: Time as a River panel (AE)

The idea I had for this panel is based heavily off the idea of time as a river.

The triptych panel would show either an actual river or one that is animated, with the flows highlighted using the particle effect. It would show a large clump of particles enter the screen from one side, moving slowly at first, this clump of particles would follow the flow of the river at first but then would enter turbulent flows, and begin to move faster and as the flow becomes more turbulent the clump will break apart/down and disperse into nothing, representing the end of time as we know it. the process would then repeat itself.

I would need to get to grips with moving the camera relative to the image (as we learnt in the animating the still volcano tutorial) so the viewer will follow the flow of particles. And if possible to break up the monotomy of this continuous loop by coding the particles to appear as different colours, and or, to change the motion of the turbulent flows each time.
