It seemed clear to me that the particles were reacting to centrifugal force, rather
than any
pre-built-in force (such as being shot from a canon, or water compressed emiting from
a
fountain). Hence the rail.. the motion of the emitter (which travels along the rail)
at any
one point dictating the direction and velocity of the particles at the moment that
they're
emitted.

And I like the camera motion, though I would agree that it's not strictly neccessary.

All the best,
