I've done my picture.

If you want to look at it, just look at
http://natureh.free.fr/mirror/Img1-Demi-final.jpg (or
http://realitydesign.asn.org.uk/index.php?page=media, where you can find
other picture and animations rendered with POV-Ray 3.6)

This pictures and anims has Copyright, and free use is not permited.

We see rather well the 'trick', but le goal is not to have something perfect
(not enough time), but not that unreal too.

It had been rather tricky to obtain this result... I had to generate a
render with transparent background ("Output_alpha = on"), without table nor
wall, and a rendering with only the shadow that interest me ; "Output_alpha
= off", white background, white wall and table, the other objects are
'flagued' as 'no_image' (they are not rendered, but theire cast shadows are
!) -> the result is used as masking chanel in the photo retouch software
that do the compositing (real life photo as background, dark grey with alpha
chanel follow, then the objects rendering with it's own alpha chanel).
