skinr libraries

Hi guys :) I've just watched a couple of Skinr screencasts, checked out the Skinr.org website and the Skinr Project page but I haven't been able to find anything like the Skinr Libraries that I've heard mention of in the screencasts. More specifically, Jacine mentioned a few times that she'd like to have a repository on d.o for people to upload skins that they have created, like the 960 grid she used in one of her screencasts.
