Well, Spider mailed me his glass tree, so I played around with it and this
is what I got.  The photons from the tree itself are over-focused by
the time they get to the ground (to the point that they diverge and can't
really be seen).  The effect from the mirrors looks kind of cool, though.

The second picture is of a blob... somebody mentioned that blobs didn't
work with photons?  I beg to differ.  This is a modified version of the
blob.pov scene that comes with POV-Ray.  I've included the source, since
it is a good example of shooting-density / gather radius relative sizes.

That's what I came up with for the tree scene too.  I kept trying to get
some sort of focused caustics from the tree.  Now I don't feel so bad.

Now I feel 'tupid...
I've tried a lot on that tree, to get something right.. Well, that's what I got
from a bad test.. Next time I'll try and stick to a sphere. 
Well, thankyou all for the informations, and yes, the mirrors look really nice.
