Inspired by eriol's KDE 4 mockup, i made this mockup of my own for KDE 3.5. I dont think style can be done.
However, the window decor should be simple. But, personally i do not know how to do the coding; i tried, i have no programming knowledge.
I am looking for someone interested in helping make the window decor. It would need no masks and the button style i pulled from clear look.
