Yup. Actually quite annoying when one tries to use photons.. :) OTOH, it
shows (or suggests) that photons actually _work_ in megapov.

But even though light has 'difficulties' (:) passing from the inside to the
outside, is can easily pass from the outside of the 'walls' and into the
brilliant. (For example if the light comes in at a perpendicular angle.) But
what happens to the light then, is much more difficult. I suggest trying to
use media that scatters the light from the brilliant to see where it goes.


Simen.
