ack! you butchered my poor filter! lol. but, you did it in a good way! this is really superb! i'd use this myself if i were doing textures for 3d and so forth.
it's interesting the different approaches we both took for revisions of the curtains and drapes filter. when i blended yours to mine, i simply added yours in as a sort of blend to mine, overwriting in part. in yours, you cut out everything but the ripple/fold part of my original and added yours in there. clever. it does make a more coherent, simpler filter of it and a cleaner look. nicely done!
and in fact, this sort of revision could open a lot of doors. using the original filter here as the base and doing what ahimsa/manon did, you could do a sort of modular thing, where one simply plugs one 'module' or 'code group' into another. i suppose that's what snippets are all about, so this isnt a completely new thought, but it is a sort of twist on that idea.
in fact, i could probably submit as a snippet that portion of my filter that ahimsa used here. call it the 'ripple/fold' snippet. and i'm guessing that other authors could do the same thing with some of their filters.
If wishes were horses... there'd be a whole lot of horse crap to clean up!
