This is an excellent demonstration. But while it proves the usefulness of
radiosity, it gives no information as to how this can be achieved. I suggest
posting at least the sources, and - if you feel like it - some form of tutorial.
Two suggestions:
1) Your comments in test 1 give the impression that one can go beyond recursion
level 2. As you probably know, this is not possible.
2) I test 3, I suggest covering the back of the reflector with a darker layer.
Otherwise its shadow looks weird.
