It might be interesting to make two versions of an image: one which goes 
into a lot of very tiny details but is "perfect", for example, having 
books on a shelf perfectly aligned, papers on a table in a stack 
centered in the middle, etc, as well as a real-world version with the 
same level of detail but with randomness and noise introduced into the 
scene: knots in wood panels, leaning books, scattered pens/pencils, 
smudges of dirt and dust, etc.

The granite and wrinkles patterns are examples of fractal noise, as well 
as the turbulence warp, etc. In MegaPOV, you also have Ridged and Hetero 
Multifractals, and can make fractal noise patterns with the function {} 
pattern.

There is someone working on a shader patch...it isn't a simple addition, 
however.
