If I had better video the black background might be cool. But I admit I'm a sucker for transparency/translucency. I don't mind a fractal flame wallpaper. But for window elements opaque doesn't grab me.
I remember there was a theme for OS/2 that was so 3D that dialogs were not only beveled, but riveted.
Funny how styles fluctuate.
Edit: I've gotten lazy and left icons on my desktop. ( A W8 Laptop btw. )
