Well, it should have been happen someday: to the collection of Python
programs for conversion of bitmap into POVRay solid objects mosaic two
more programs (p3zaika.py and p6zaika.py) were added, converting bitmap
into a pack of triangle prisms or hexagonal prisms, correspondingly
(sample output of p6zaika attached).
All programs reside at
https://github.com/Dnyarri/POVmosaic
and may be used, modified and tortured for free.
So, currently spheres, cubes, and two sorts of prisms are included as
mosaic primitives, and all regular plane partitions (3/6, 4/4 and 6/3)
covered. Considering the fact that POV output of these is as flexible as
I could imagine, so you may edit objects properties or even replace
objects globally, there is a vast opportunity to produce mosaic-looking
posters, greetings cards, ads, and, all in all, molest humans
graphically. Enjoy.
Meanwhile, while POV primitives seem to be exhaused (more or less), I
may probably continue with something more complex. Beware.

This is a good shot, Ilya!
Now, you can use each kind of shape, like in the old GIMP filter.
Interesting work.

If you take a look at these programs output, you'll see "thingie"
declared. That's the basic object, mosaic element. Later it gets color
and finish added, is scaled, rotated and moved where necessary, but the
same object is used for all mosaic. Therefore, you may replace it with
another object once, and it will be replaced throughout the whole scene
(just take care about it's size. For spheres and boxes it's 1*1*1, for
others described in the file), using the same symmetry as original.
About the only thing I don't recommend - using too complex objects.
Surely, you can edit POV file produced by my program to add .inc with
very complex object, and it will work (I've tried with spline
figurines), but very slowly.

At the moment is difficult for me to spare some time to code, but I will
surely get a look.
A nice work!
