I'd like an iPhone app icon designed for my app. The icon should reflect what the app is about i.e. letting people track their moods and see how happy they generally feel.
I'd like the icon to have a positive/happy emotion to it. An obvious way to do this would be using a smiley face (as per the smiley face in the actual app, you can see it in the screenshots) but I want something more interesting than just a standard yellow smiley face.
