I certainly can. There are aspects of what you describe which I apply
to my work. However, I tend to prefer a more "active" approach to my
browsing. Sometimes though that actually means I can't get to sleep as
my mind is still switch on!

Ah, I see. Have you ever magnified an image digitally? Then you will
what are talking about.

Well, as I've already stated - this was never about arguing for the
use of JPEG2000. I merely posted an image in that format because
that's the format I thought best represented what I needed to achieve.
The advocacy came later after the rather odd responses I got to the
posting.

See above - ah, looks like I might be repeating myself in this thread.
Oh well.

I posted a comparison image. It should still be on the server. They
were certainly noticable and not want I intended at all.

In this case, it had to be JPEG2000, there were 16-bit colour and
artifact issues that needed addressing. Though now it seems that the
16-bit aspect of all of this may be pointless as the ability of
hardware to support this may be lacking, plus there's the possibility
that lossy compression does not help when used with 16-bit.

No, it's true. I mainly use Bryce and Poser. I only use POV when I
have a procedural effect in mind - one that really could do with
scripting to help it into being.

I'm not sure. I think there are a number of various standards for
different things out there that bear oldish looking dates. However,
it's the implementation wake that follows that is important - I think
we are about to get the full swell of that soon.
