# Tours of the Universe  Anything in WWT can be included in a so-called guided tour which looks like a video with narration, music, text, graphics and hyperlinks. A tour has the distinct advantage over video in that a tour is interactive at ANY time. When paused, the user is in the environment and free to zoom closer into a detail, or switch see what that object looks like in other wavelengths, find more information or branch off on another related tour.  mention re-creation of Galileo  Huchra Tour
