Twitter has a streaming API. Using that we can extract tweets. Students need to create an application to extract tweets about Google Code-in. You need to show them on a map. When a tweet received, that should pop up in the map, wait for sometime and disappear. Tweets about GCI and FOSSASIA should be marked specially.
