That's an intriguing idea-- sort of like duplicating the many *tiny* water
droplets that constitute thick fog. With variable sized-spheres or different
IORs. Food for thought :-)

Certainly possible, although I *think* the slightly larger object would still
look distinct/sharp. I'd have to experiment to find out.

I actually don't know if a POV-Ray lens-type object will cause 'blurring' the
way a real lens does (which is a combination of the lens itself and the eye's
inability to focus on the resulting 'aerial image.') I've never tried testing
such a thing in POV-Ray. I *suspect* that its camera will always keep all rays
sharply 'focused' (so to speak).
