Ah back in the early 2000s life was exciting on the Linux desktop with weird and unconventional artistic window decorators that would make plants twine around your borders or have short beOS-style tabs or put the close buttons bottom right and so on! Customizing the desktop was a major time-sink for the students at my collage. :D
In fact, by comparison with how I recall Linux desktops in 2000, these KDE 2 screenshots seem to be ushering in a new era of boring conforming window decorators :(
Where have all the crazy interesting rebelling different decorators gone? I did a quick flick through gnome-look.org and found nothing very different.. :(
