LOL, yes this one comes into mind.

Bill did a very interesting work here and I really would like to learn more
about its creation. I have worked a bit with df3 recently and experienced the
one or other difficulty. I wonder how the df3 is created. And I wonder how it is
parametrised to achieve this colors. Hope he works not overtime today...

Since I'm working about clouds a little bit at the moment (just to have a
collection of them and musn't bother about this topic any longer) I came up with
the idea to put existing figures like my rubber ducks or may be Poser Jessie or
a sailing boat into (a heavily modified version of) Gill Tran's makro as a
ground object to create the kind of clouds we often associate with this figures.
So I'm very interested in Bill's approach here.

Best regards,
Michael

P.S.: And yes Sam, you posted very interestings things too while I wrote this
post. I only wonder what has happend to the skull to look in this way. It cannot
have been a bullet... Looks great anyway ;-)

More detail on the df3 media technique used for the ghost image and a 
working example to be posted to p.b.tutorials. Here is the README from 
the tar ball:

---
The media technique attempts to avoid many of the known issues of using 
multiple media containers to create a complex media objects by stuffing 
shapes and colors into separate df3 files. Further the template provided 
(test.pov) supports up to 4 patterns, shown as rows in the included png 
file.

Each row is a media, which are added together in a final interior. In 

overlap the head shape to create a much more complex result.

The colors in each pattern row are determined by values within color df3 
files which themselves pick predefined colored densities from a density 
map. In each media the color and shape df3 values are multiplied. Where 
the shape values are 0 we get nothing in the resultant media.


df3s where the voxel values are all one value (200) existing only to 
define the overall shape. Two different turbulence warps are used of the 
shapes. These same warps are used to warp the color DF3s so the colors 
track the shapes no matter how turbulent in the end. See paintblot.png.

The DF3 files are created with a hacked tcl method based on Darren's 
MakeDF3 tcl utility which he posted to p.b.utilities.

Terrific! I guess we are both thinking ahead to Halloween... I look 
forward to seeing the source as I am not quite following how the final 
pattern works.

Very well done.
It remember me a 3D ultrasound image.

Haha, yeah :) Reminds me of something Stephen King wrote in one of his novels
(It), "walk faster, the mummy's chasing us!"

I hope to have the code all clean and sparkly soon... I don't say this much, but
Real Life got in the way :P

Great! It is an intriguing concept.
