A side project done in collaboration with a co-founder to index the web on time.

This produced a search engine for important dates in history relating to keywords, so a search for 'America' would yield the top 10 events in american history, for example  Columbus' discovery and the American Cvil War. You could then drill down to any time span to find the events between those dates.
