Hi There! shows real time tweets of people tweeting around you within a 2 km radius.
Just head to the URL and wait for tweets to appear. It only works on browsers that support WebSockets and GeoLocation.
Hi There! uses HTML5 WebSockets and GeoLocation technologies. The server connects to the Twitter streaming API with the ntwitter library (https://github.com/AvianFlu/ntwitter), and pushes tweets within the user's area range via WebSockets using the ws library (https://github.com/einaros/ws). The webpage is served using Express.
