Xfwm4I did some theming around the original theme of Xfce 4.4.
All I wanted was the title bar to be a bit smaller. I managed to reduce it from 6 pixels. Then I simplified the buttons. The work was quite long with redundant actions, well it is what it is. Now I have my theme :)
I posted my modifications at Xfce-look.org.
ajaxMPI also did a theme for ajaxMP a little time ago which is based on Xfce-dawn theme (which is my current theme moreover). ajaxMP is a web interface for Music Daemon Player. I already mentionned it in the post "My current apps".
I am also working on a web design in black for a french rap production. They have very good instrumentals and I am sure the CD they are producting will kick ass. However I prefer good old Pink Floyd at this time.
