If you have Object Desktop (www.objectdesktop.com) you can download and try out the first alpha build of DesktopX 2.
DesktopX is a program that lets you design your own Windows desktop. One of the highlights of DesktopX 2 is its ability to automatically inherit your existing desktop (the icons on it) and add all kinds of visual effects to them (shadows under icons, desktop icons that are any size, icons that smoothly animate to a bigger size when you put your mouse over them, sound effects, etc.).
DesktopX 2 also has a much cleaner user interface to make it easier for people to design their own desktops.
