I have found a use for the ludicrously wide panorama, entitled Wall of Ships, that I created last year. It looks nice as the backdrop of my first Firefox Persona.
Firefox Personas are a really neat and simple feature that has come out of Mozilla Labs. It's a way to theme the browser by providing a wide image for the top and bottom of the browser. Very easy and effective. This is a good example of how a simple but well executed feature can have a big impact on user experience.
