Found this, anyone know where it is from?

Some brilliant entires in that list, I've been searching since to try and find something just like the one I'm after but it's proving difficult
Usually the developers who include these on the websites will find an example online, then strip the css out and images etc until they have it in it's basic form. Once here they then begin to rebuild the css using there own design. So I think anyone will do the job, I guess what you would want to look at is the code itself how clean it is, load times etc.
