That explains why you are not able to use radiosity, memory use would be
much more intensive then and swapping is quite impossible, even if the
total amount of memory used is not larger.

Not compared to some other utils out there.
An old DOS package called SEA can give better looking results with a
smaller file size.
Look on http://www.photodex.com
There's also a thread here in p.b.i as follows which may help you.
Always assuming you can find it :)

Not to poke holes in your dreams, but why not just go for the 1.33Ghz
Athlon, and save a bit of money towards the memory for the sake of 66mhz
(What am I saying?! My first PC capable of running POV only had
66Mhz...)
Oh well, just a thought.

(little bit OT)
I said "dreaming of a 1.4 Ghz Athlon".
But let us be rational. I have had renders which lasted up to 3 weeks.
of my monitor and counting minutes for rendering a single line.
I swear, every second counts.
Therefore I will pay about 100 Euro (ca. 83 $) for 5 % speed gain. This are
only 4 to 5 % of the whole desktop. I think, its worth.

It is just my two cents, but I think you should concentrate on the
picture and not on submitting it. It is a really stunning picture, so
natural, so realistic. And of course it would become even more so with
the addition of some insects. But it would still be a landscape
picture and not an insects picture.

Indeed. But you should somehow put the focus on them. Insects are
small. If you want to have one close-up, and still have a realistic
picture, you'll have to use focal blur... and that would be a great
loss, considering all the details that will be lost.
>I had two solutions in mind.
>First a part of a tree with bark and a bug climbing the trunk.
Or an insect half-drowned in a sap drop? That would make for an
interesting raytracing showcase. Maybe when you buy that Athlon...
>Second a big flower like a hemlock and a bug and ants.
How about a branch in close-up and a spider web with a spider and a
fly in it? Or maybe a caterpillar pretending to be a piece of bark? Or
a cocoons of sorts. Two fighting (or mating) praying beetles. You can
also try a cliche, a fish catching a mosquito.
That's precisely what I am pointing my finger at. You are obviously
very good in coding, modelling, texture and lighting. You have to be
at least as good in composition to make the picture so that the focus
is on the insect, it is large enough, and none of the detail is lost.
>So I have to choose a flying insect.
See my other suggestions. Maybe you could use a little spider hanging
on a thread somewhere in the lower-right part of the image.
>Since I have no experience with motion blur, I have a butterfly (or two) in

Try putting them on a water lily, two of them. The bright green and
white of the lily would make a great background for some vivid yellow
or red. Just a suggestion.
Once again, outstanding work!

Put the whole grass in a union (not the triangles, the meshes :) ) and
give them an appropriate pigment. I think large-scale granite, or a
perlin-like average of a few bozos, would work great.

I suppose it's a matter of personal choice in the matter.
And on that note I shall shut up :)

Hmm ... how about about an insect picture without any insects visible?
Change the lighting so that it looks like early evening, and everybody
who doesn't hear the buzzing[1] of mosquitos lacks imagination :-)

call the sound that a mosquito makes?
