Unity looks familiar
Mm, am I the only one? Did you get an eye on this “revolutionary interface” for Ubuntu called Unity? Doesn’t it remember a lot on WindowMaker? Ok, it’s not enough talking about “little squares” that launch things, but they could improve the dock to be a bit different than tne old-school MacOS or GNUStep one. Have a look and compare (btw, windowmaker is the one at the right :D):
