Actually no... the objects are transparent, so we can see the interior of the
objects... Isn't there a way to accumulate the colors instead?
I guess that for a real motionblur I would need a 3rdParty...

I had tried a crude method of motion blur for POV-Ray 3.* and the object
transparency (or opacity) had to be adjusted for allowing of the overlapped
object "clones". The tendency, without adjustment, caused a brightening of
the filtered color.
It's of no use anymore, and was never really good anyhow, but a zip of the
files is at:

Yes, that's another bad thing I didn't think of. And it's a lot worse.
: Isn't there a way to accumulate the colors instead?
Yes, using the motion blur in MegaPov.

Yeah, now I think about it, that makes sense.
