I’ve had numerous e-mails and I’ve seen comments posted about the latest themes I have been using in my past few screenshots. The sawfish theme is called “spiffDOME” (as it’s based off of a nice *dome engine and is a more modern version of the spiff* series) and the Xenophilia-based GTK+ theme is called “Athens”.
You can see both of the above themes in action in my “angular” screenshot.
Enjoy the themes!
Update: The background is also available.
