I would like to inform that POVRay mosaic collection of Python programs
was completely rewritten, hopefully providing more flexibility and 
simplicity for end users.

POVRay mosaic is a set of programs, which read every pixel of source 
image and convert it into a 3D object, colored after source pixel, 
together with neighbour objects, thus creating something like 3D-mosaic. 
Object properties (location, size, rotation) can be made dependent 
(mapped) on source pixel brightness.

Several old programs were converted to just two: 3zaika and 4zaika, 
packing objects into triangle and square grids correspondingly. Main 
idea of rewriting was compressing all variables, introduced into initial 
versions, into compact set of #define objects, vectors and stuff. For 
example, default output of 3zaika is a union of tightly packed spheres, 
but you can turn it into perfectly packed hexagonal prisms by changing 
"#declare thingie = thingie_1" to "#declare thingie = thingie_4" in the 
"Selecting variants" section of exported POV files. Similarly you can 
switch predefined finishes and transfer functions. Surely, you can write 
your own - easiest way is patching scene with preset.inc files (some 
examples are provided). Some rendering examples are provided at 
in corresponding sections. Help file, describing options in presumably 
human-compatible form, is included.

Hopefully you'll find it funny enough to start boring your friends with 
mosaic pictures.

Suggestions on extending are quite welcome.

Excellent !
I like the cylinders as basic form and different angles layout.
Looks like it's possible to implement fur this way.
