A quick Twilight Sparkle-style Google Chrome Icon.
Idea from [link]
I decided that I wanted the same kind of thing, but with Twilight, so I did this. (I don't have much of her on my desktop.)
NOTE: This is a PNG file, so it's compatible with both Mac OSX and Windows. If you are changing icons on the Mac, I suggest Candybar. There really is no comparison if you like to change a lot of application icons like me. I haven't really looked into changing Windows icons, but software is most likely the way to go as well.
