How about this ice. I work over it (and snow too) for 5 days :).
It's a part of my "complexity" entry.

But without blue sky and radiosity snow looks ugly.

Thanks.  It seems the voters don't seem to think so though.  All 3 of mine
are currently around 5.5/10.  Not that I think mine are fabulous, but I
think they are better than that, especially looking at a lot of the higher
ranked ones. Either a lot of voting down or maybe just really critical
voters.  Oh well, as long as I've enjoyed making them.

I may try out how your suggestion looks as well.

Here is an attempt to diamonds (and a humble contribution to the 'rendrering
lull' topic). After a quick look to gemologists sites for the cut angles.

Looks pretty good to me.  What kind of ior are you using?  Trace level?

Reflective spheres, superellipsoids, torii, blobs, and *lots* of fairy 
lights still to come... :-D

Already I'm making a railway with the train and bridge. Camera is located
under the train a little from back. There is also an old destroyed "High
Voltage" sign laying on the rails. there are first renders. I'm waiting for
comments :).

Yes so did I, it turned out like quite a good idea.  But I guess it isn't 
something we can do every week...

Hello.

I posted in p.b.s-f my include file for diamonds macro, and here is the test
file for the image (maybe not exactly the same parameters):

// Persistence of Vision Ray Tracer Scene Description File
// File: diamond4.pov
// Vers: 3.5
// Desc: Basic Scene Example
// Date: december 2006
// Auth: Bruno Cabasson

#version 3.5;

#include "colors.inc"
#include "diamond.inc"

global_settings {
  assumed_gamma 1.0
  max_trace_level 50
}

// ----------------------------------------

camera {
  location  <0.0, 0.0, -6.0>
  direction 1.5*z
  right     x*image_width/image_height
  look_at   <0.0, 0.0,  0.0>
}


light_source {
  <0, 0, 0>            // light's position (translated below)
  color rgb <1, 1, 1>  // light's color
  //parallel //area_light x/5, y/5, 3, 3 circular orient
  translate -20*z
  rotate 90*x
}
// ----------------------------------------

#declare TILT = 25;
object
{
    makeDiamond(Red, 0.99, 15, 0.07)
    rotate -TILT*x
    translate y
}
 object
{
    makeDiamond(Green, 0.99, 15, 0.07)
    rotate -TILT*x
    translate 1.2*x - y/2
}
 object
{
    makeDiamond(Blue, 0.99, 15, 0.07)
    rotate -TILT*x
    translate -1.2*x - y/2
}


Here is attached another instance of a diamond with photons.
