Message: <404c8ded@news.povray.org>
Another stab at the LED Panel but with only Radiosity lighting this time.  I
prefer it, although there appear to be some odd lighting effects across the
tables surface, almost as if there are overlapping light sources ( theres
only one light ).  Does anyone know what might be causing that?

I'm using the box at the bottom of this scene to light it.
