Thanks a lot Robert! I can see were I go wrong in my code!
I am in the learning process as these are my first time ever photons :-)

Got them!
A crude render as test but I got the caustics right now. They show on
the ceiling.
Thanks to Robert showing me the way.
Comments?

I thought all objects defaulted to "collect on" anyway? Could this be where I
have gone wrong with photons in the past?

First attempt.
I am replacing some of the objects with ones more suitable for Pov.
Sphere{}.
Isosurface for water.
Copies for Mesh2{}: chair, floor tiles.
Todo: CSG door, shelf, and pool.
Comments welcome:

I thought so too indeed. It looks like they do /not/ default to this. As
far as I know, this is not mentioned in the docs.

Note that the use of fog{} is killing the caustics.

Indeed. POV-Ray help in chapter 3.4.4.4.2 says so and therefor I didn't
see anything wrong with Thomas' code. And POV did behave like this back
in the past.
I was just a lucky to add collect on/off anyway anywhere.

Maybe the default has been broken then?

Still too dark but that can be amended easily. All objects do not need
to be replaced by mesh2{}, only those which need proper tweaking for
photons and such but it is a rewarding exercise nonetheless.
a water isosurface might be a good move indeed...
