Ha ha, I actually thought that was a render and was in awe.

I am still of course in awe of your other work but at least my desk is tidier
than yours ;-)

Oh my... I thought that too! :D :D :D Earlier today I was in a bit of a hurry
and didn't pay more attention. xD

Nevertheless, kudos to Mike's work, amazing stuff indeed! :)

Radiosity tend to dislike scenes with a lot of reflective and 
transparent objects.

If that's your case, it MAY be worth it doing a multi-pass render.
A pass without most of the reflection and with the transparent objects 
removed where you save the radiosity data.
Use higher quality radiosity settings.
Then, a second pass with all the reflections and transparent objects 
where you load the previously generated radiosity data. Use relaxed 
radiosity settings.
As I have no personal experience with that technique, I can't give you 
advice about the details.

1) A bit old by now maybe, but I guess still valid for current versions:

http://news.povray.org/povray.general/thread/%3C4e81db88@news.povray.org%3E/

2) The attached pdf is a compilation about the subject, starting in 
2008, but towards the end there are some more recent tips and tricks 
which may be of interest.
