everymomentnow is a beautiful news visualization site designed and developed by Craig Mod. The idea is to provide a sense of volume and correlation between keywords within a given subject area. The current incarnation focuses on Obama/McCain in the news.
The clean, minimalist interface allows the user to visualize spikes in news article occurrences for each keyword a the highest level. You choose a single focal point using a keyword (e.g. Obama or McCain) or a date restriction, and the site displays the news articles indexed for that entry point. A much richer interface is also displayed for exploring the set of news articles by other keywords associated with the current keyword/date focus. So you could look at Obama + 9/16/08, or Wall Street + 9/16/08. Presently the interface doesn't allow for a combination of multiple keywords, e.g. Obama + Wall Street + 9/16/08.
