NoNameRetro theme is based on NoName by TheRob. (The biggest thanks goes to him for all of his hard work and willingness to allow these modifications.) This theme is based on an early “beta” version of NoName, so the look of the Metacity window border is significantly different from the current NoName theme. There are quite a few changes to the GTK theme as well. As far as I know, all the work on which this theme is based was released under GPL.
