Well spotted - the glass sphere (as well as the glass statue) simply use
"interior { caustics }" to give some impression of the light traveling through
the material.

I haven't got around to trying photons yet in my rig - it may well work by
taking a very low number of samples, since in effect you end up with 400 times
as many if you do 400 passes.

Cheers,
