Everything changes with time, and a clever visualization of this comes from William Huber who took every cover of Popular Science from 1882 to 2007 and plotted them  in this massive graphic.

By arranging thousands of magazine pages into single high resolution images, we are able to reveal gradual temporal changes over long historical periods.
