Wish granted. I put a SPLASH.ZIP file in pov.binaries.scene-files.
Note that I don't have a clue about what the variables do or how this code
works.
It's not made to work in an animation apparently, but 1) I could be wrong and
2) there's no reason why it couldn't be done by someone at least as clever as
the code's author.

Yes, it's a real pity, because the Pov scene seems quite lively in Japan, and
lively enough to support 2 consecutive Pov books. And our Japanese friends are
quite talented with Povray, art-wise and math-wise. They keep up with the latest
developements, have a lot of stuff translated and so on. From my discussions
with Tsutomu Higo, I understand that many Japanese povers think they do not
speak english fluently enough to participate in the english-speaking newsgroups.

I surely would like to hear from them more often, because the povray community
could benefit a lot more from their experience and talent than it does
presently. For instance, it took several years (and Ron Parker's Superpatch) for
Ryoichi Suzuki's isosurface patch to become popular.

I see what you mean, I totally missed it until I saw the smaller version
in the gallery.

I've seen Tsutomu(Tom)Higo's site before but not the others. Thanks
for sharing the links, there's some really nice stuff out there.

Some interesting stuff here, I will have to take a closer look later...

A bunch of objects in an array, rotated by an amount depending on their 
position. You can see that they are really arranged in a rectangular 
grid, with every other row offset a bit(OK, a hexagonal grid). I was 
able to recognize the effect because I did something similar with one of 
my macros and some cones, but it wasn't anywhere near this good.
I'm not sure how the face effect was done, although I can think of two 
possible ways: A pigment using an image map, disguised by the 
reflections and rotations, or the reflections themselves of an image map 
on a plane behind the camera. It is hard to tell, and the varying colors 
don't make it easier, but I think it would be nearly impossible to get 
the reflections aligned properly. It is probably an image map buried in 
the texture, either way it is a great effect.
It is kind of...shocking...to see that in what is at first glance just a 
geometric design.
It makes a good desktop pattern, too, if a bit-dizzying. :-)

Also check out the isosurface patterns in Gallery 4.

That splash effect looks very familiar for some reason, I don't know 
where else I could have seen it though...

And it also gives a way of doing sparks and lightning with media which 
is much better than my lightning macro.

I am just taken aback by the brilliance of these people. God bless 'em all.
I wish they could share with us and participate. I was humbled by my trip
through the many links Gilles provided... were you?

Nothing like a good old fashioned language barrier to get in the way of
progress.  I have a niece that took a Japanese language class and my dad was in
Japan a while near the end of the Korean War and he still knows some of it too.
I can't remember any Spanish or German I had in school.  I have seen a few web
pages of Japanese content about POV-Ray many times before which almost had me
installing the font for them even though I'd never be able to read it probably.
Would just make them look better I guess.
Wonder what the actual number of languages is that would need to be known to
converse with everyone using POV-Ray. Too many?

My guess is that the objects are rotated relative to the lightsource to
show a certain amount of shadow to create the shades of colour for the
image. It's so subtle I missed it at first...

Bonsoir Gilles,

Thank you for posting this very detailed list of links.

Thanks also for the water drop source.

This is too bad in my mind. I, for one, would welcome their participation.

>After all the pov-script is international.

Yes!

Thanks, again,
