Nice Illustrations, i like them :)
i never got media-photons look right..
i always imagined them looking that way :)

I have one suggestion though, could you make the parabolic mirror
a good amount shallower / the curvature less? Then one could see
the focal point of the mirror better. You could also place a
lightsource at the focal point (or slightly off for comparison) to
see the reverse effect (like a flashlight).
