I did give a list, categorize them by intended purpose: pattern, 
component of other functions, isosurface.

Ok...functions are useful for more than just isosurfaces. You can also 
use them as patterns and as pieces of other functions.

Category: Patterns(functions intended to be used as patterns)
        The Patterns category requires the function itself, a simple 
description, and a preview image.

    Sub-categories:
    Noise patterns(anything that is similar to granite/bozo/wrinkles)
    Wood patterns
    Geometric patterns
    Other patterns


Category: Building blocks(functions intended to be used as parts of 
other functions)
        Requires the function itself, and a description. May have a 
preview image.
    Sub-categories: none


Category: Isosurfaces
        Entries in this category require the function, sign, and 
threshold value used, a description, and a preview image. Information on 
max_gradient and contained_by would also be useful. In fact, everything 
other than the texture and interior would be useful.


Category: Parametric surfaces
        Objects done with the parametric object. Requires a description 
and image, as well as the object minus texture and interior, like the 
Isosurfaces category.


You may also want isosurface and parametric categories in an object 
library, because you can make many interesting objects by combining 
isosurfaces and textures.
