fvwm-2.5.something on my notebook. Mrxvt (with transparency) with the desktop showing through. The image in ImageMagick was captured with xine because import wouldn't take the picture correctly while xine was running.
FvwmButtons artwork comes from
the Ty official site. I took the boomerangs off with The Gimp, then made the mouseover images with text added via ImageMagick; the text shows what each mousebutton does, and the top image currently has the mouse over it. Oclock in one corner and FvwmPager embedded in FvwmButtons. Down the left side is xbattbar.
