Navify is a new mashup of Wikipedia, Flickr, and YouTube. Like Nibipedia and Visual Wikipedia, Navify attempts to match videos and images to Wikipedia articles. To use Navify, simply enter a search term just as you would on Wikipedia. The results of your search will be shown in a three tab display of Wikipedia article, related images, and related videos. The screenshot below shows the results page for my search for WWII.

What I like about this type of Wikipedia and video mashup is that it provides a second or third option for students to get engaged in learning. A student that struggles as a reader can still get engaged in an article through the corresponding videos and images.
Visual Wikipedia is still my favorite mash-up of Wikipedia and videos because of its web-style of information discovery. That said, Navify is a very good resource for finding visual aids to complement the topics that your students are studying.
