Newsmap: This site displays a visual search of the world's news. It displays the news of the day and will colour code results by topic such as 'science', 'technology', business etc. It will also colour code those individual topics based on how long ago the story was posted. The darkest of each colour (topic) was posted more than an hour ago, while the lightest, displays postings of less than 10 minutes ago. You can toggle on or off individual countries to find certain news reports or current events. It also allows you to search by topic (top right of row). A simple mouse over of each box will give a brief description and then you could choose to click/select it to follow that news item.
This example has Canada selected (top row) and presents all topics (bottom row).
