The images on Google change with the news surrounding your search term. If I were to search Osama Bin Laden now, it would result in different images depending on the news surrounding him. There is a big difference in the images before his capture, and after.
I used this to create a newspaper that consisted only of images. The news headlines were replaced with the images results of Google. This created a language that changes with the events in the world. A trending topic in the news automatically changes the images that can be found on Google. This is then immediately visualized in the Newspapers images.
