I found an icon pack for those of you interested in ponifying your desktops, if you don't like the assignments of the icons there's nothing to be done for that, but overall I found the icons to be pretty great, and you can always use one icon for a different type of program.
The better quality images are for Mac users unfortunately, but I took the liberty of converting all the icons to .ico for Windows users anyway, since I had to do it for myself:

Credit goes to this guy
for the icon pack.
Also I just came across this, seems legit. If you don't like the intro then this is most likely not for you.
