I used to use one called Bumptop that was very powerful and a bit of fun, but in the end I went back to 2d just because it is easier to keep organized. I was in 3d mode for 1.5 or so years so my actual 2D desktop (when I went back to it) was cluttered with so many icons it literally took up more space than there was on the monitor and I had to delete multiple screens of icons.
