Qwiki is a pretty amazing website where users can type in a search term and the site provides multimedia information about a topic.  Additionally, Qwiki also links to related resources.  For example if you type in “Sacramento” into the search field, multimedia explanations of John Sutter and the California Gold Rush will appear at the bottom of the page in related resources.  Natively, the Qwiki website will not work in Safari on the iPad.  However, Qwiki has developed a free app that is worth reviewing.
