^if im not mistaken, that's dock with some word-wannabe-icon (lol, idk how to call that thing)..
lookie here for an example..
if you good enough in photoshop, you can do it your own.. seriously no kidding..
and do correct me if im wrong

^bleh, you can use whatever suit you..
as for my personal favorite, i use rklauncher..
lookie here for another dock for winxp..
as for how the pictures work, save your work as png and apply it as icon..
