I really love pretty much anything Jessica Hische designs and her new set of Snow Leopard icons are no exception. These icons are beautifully simple and would be a welcome replacement for all the over designed program icons currently living in my (and any one’s) dock.

How to install the icons from Jessica:
I highly suggest everyone skip trying to do it manually and instead opt for Candybar, an awesome application by Panic. You can manually adjust almost all of them (by digging through the resource folders and replacing the .icns files), but on some of them it was a bit tricky and took some figuring out (like the finder is impossible to change in Snow Leopard apparently, but easily changed in Candybar).
