There are two movies: one by Tarkovsky, which is far the best one but rather
lengthy and sometimes cryptic, but follows well the book; the other is a US
remake from a few years ago, but where the focus is shifted to the love
story. I only saw the first one (and not completely...). From what you
write, I suppose you have seen the Tarkovsky one? :-)

So I thought... but hey! It's just a piccy...

Well I only knew of the new American remake - didn't know there was another.
All that was nice about the recent US made one was the music. But, I
suspect, like all films of published books, the film will always
disappoint...

Usually, to liquefy a gas, you either raise the pressure or lower the
temperature (or both). So no, it can't be a liquid under higher
temperature, unless the effect of the pressure is more important. There are
some substances which melt (from solid to liquid) under pressure (water is
the paramount example), and recently some mixtures have been discovered to
solidify when heated, but I'm not aware of such "strange" behaviours
existing for the liquid/gas conversion.
According to google, some usual freons have boiling points around -30
degrees (Celsius or Fahrenheit, they're the same at -32) at 1 atm, that
means they can be liquid under normal pressure and not too low temperature.

I stand corrected... but the image still stands... get it? The image still
STANDS...
Geez I suck at 0235 in the morning.

I found this site about Lem's Solaris, with renders of the Ocean in Bryce:
http://www.hansego.de/LEM/Solaris_1972/solaris_1972.html
Interesting. However, I think we can do better in POV :-)

Hmm - those images look pretty nice anyway...

True. I like them too, and they are pretty close to what Lem describes.
Still... I am thinking about isosurfaces, meshes, and media... I am
currently re-reading the book and I admit that often Lem is confusing or
contradictory in his descriptions of the Ocean, and particularly the strange
artifacts it generates (mimoids, symmetriads, extensors, agilus...).

Greetings, Lensman!
FWIW, I sell disposable contact lenses. :)

Hi Thomas,
Sorry I didn't reply earlier - I've either been too sick (with the flu) or
too busy at work.
I've been reading a lot of old "Astounding" mags from the 1950s recently.
Now I'll have to reread all those Lensman stories again. :) The first time
was more than 30 years ago, so I'm sure I've forgotten heaps.
To render a Lensman's Lens would be fun... I guess it will take media and
animation to do it properly. I just did a quick Google Image search, & it
doesn't look like anyone's tried to do one yet...
Also, it'd be fun to do a Doc Smith style space battle, but I doubt I have
the memory for thousands of space ships arranged in concentric spheres.
