Hi all:

     I finally found a simple way to create an endless stream of 
wallpapers for my virtual rooms, using the new tiling pattern type 5 
(thanks, clipka!), combined with repeat warps in a texture_map.

     Here are a few samples attached. For these I used a William Morris 
wallpaper design as input, but almost anything can be used (including 
procedural textures, of course).

     If you enjoy repetition, try the following code at your own risk... ;)

// +w665 +h768
#version 3.7;

// change the seed until you find a nice result (shouldn't take more 
than a few tries)
#declare r_pattern=seed(745);

// name of the PNG image to be used as a base
// the URL below doesn't works obviously, is just a recommended image source
#declare 
imagemap="http://upload.wikimedia.org/wikipedia/commons/e/ed/Morris_Snakeshead_printed_textile_1876_v_2.jpg"

// and the desired scale for it...
#declare im_scale=5;

// create the random base texture
#declare t_base=
texture{
     pigment{
       image_map{jpeg imagemap interpolate 2}
       rotate 90*x
       translate rand(r_pattern)*x
       translate rand(r_pattern)*z
       rotate 360*rand(r_pattern)*y
       scale im_scale
       warp { repeat .5*x flip x}
       warp { repeat sqrt(.75)*z flip z}
     }
     finish{emission 1}
}

// tiling
plane{z,1
    texture{
     pigment_pattern{tiling 5}
     texture_map{
       [0   t_base rotate -120*y]
       [1/3 t_base rotate -120*y]
       [1/3 t_base]
       [2/3 t_base]
       [2/3 t_base rotate 120*y]
       [1.0 t_base rotate 120*y]
     }
     rotate -90*x
    }
}

// render it seamless
camera{
    orthographic
    up 6/sqrt(.75)*y
    right 6*x
}
