I am not sure if it's today only, or if was started today, but Google has the "I'm Feeling Lucky" button on the right switching as you point to it. It switches to various ways Google searches for things. Put your mouse pointer over it and it will change from: "I'm feeling lucky" to "I'm feeling ________" and you can click on the ending "feeling" to get different random search results. I've had it change to many. Among them: doodley (shows all Google Doodles), stellar (shows stars and nebulae photos), trendy (shows hot trends). Try it out!
