638kb is a little harsh for an image of those dimensions, I suggest png or
jpg.

Had I proclivity for math, I would assist with the macro.

My apologies.

You could probably start with making a grid of spheres using two nested while
loops.  The effect in  your sample could be achieved by an increased random
displacement and leaving out some position from bottom to top.

BTW, you should consider using jpg for posting pictures here, downloading 600k
can be really boring and you could easily compress this pict. to below 100k.
Please read the guidelines in p.f-a-q.

As others have said the attachment was way too large for such a simple
image.  Please consider canceling your original message both to conserve
server space and to save others having to d/l the image some of us pay
expensive rates for our thelphone connections (not by choice, by geography).

It may be an idea to create a heightfield from an image that you've produced
in a paint package with the dots already in the right places.

Is this the sort of thing you are after?

#include "colors.inc"

camera{location <0,25,-70> look_at y*25}
light_source{0, White translate <10,10,-50>}
sky_sphere{pigment{White}}

#declare R = seed(334523);
#declare y_count = 0.1;
#while (y_count < 50)
  #declare z_trans = (y_count/2);
  #declare y_rot = rand(R) * 360;
  sphere{
    y_count*y, 0.5 + rand(R)
    pigment{rgb<0.25 + rand(R), 0.25 + rand(R), 0.25 + rand(R)>}
    finish{ambient 0.5}
    translate z * (z_trans * (1 + rand(R)/5)) rotate y*y_rot
  }
  #declare y_count = y_count + 0.2;
#end

    the .bmp is 481078 bytes;
.jpg at 100% is 141264 bytes;
     at 80% it's 51653 bytes;
 at "0%", below, 10921 bytes.

Yeah, although your "0%" seems beyond optimum.  BTW, the .bmp was more than 600k
due to encoding.  

To make it complete, reduced to 4 colors and saved as png i achieved 8348 bytes
and it looks much better than your jpg...

Ooo, a sparkly. (another movie quote;)

Is this using glows? (haven't tried 'em yet - I'm partly waiting for the
dust to settle before downloading mp6).

Mr. DeWitt,
I'd like the source to that modified image, if its not trouble.

Hi.
I'm Ian, and I'm a sourcecode addict..
