Should we include citations?
Yes, this icons correspond to Nuvola Collection You can download them from site. http://linux.softpedia.com/get/Desktop-Environment/Icons/Nuvola-23024.shtml
I've already found in WE some of these icons having different names. I kept names intact, except for some derivative works I created from them.
Have a nice day. --chela5808 13:18, 20 February 2009 (UTC)
