Hey,

>Any other comments on this?

Well, in August of this year, I did pretty much the same set of experiments,
and wrote up a short article, which you can read at:

http://www.redbrick.dcu.ie/~element/areaLights/

Now, I didn't have all my facts straight when I wrote it, and the subsequent
flame war that was targeted at me on povray.general quickly pointed out
that Povray's arealights are *not* designed to give area illumination, but
simply to simulate area *shadows*. I agree though, a source of area
illumination in Povray would be most welcome...
