fake radiosity with ZBuffer

[endi]

I have an idea.
In Photoshop I use Blur/Fade Blur to make “atmosphere” effect on my rendered images. This is good for a very-very-fake-fake-lame radiosity effect.

But I we can use ZBuffer for this effect, we can make a fake but good radiosity.

But we need a programmer.

What’s your concept and how do you think it’d work?
