Hi HN.

I've built a map that takes a geofenced stream of tweets and runs AFINN-111 sentiment analysis on them, and then displays them in real time on a map of London.

Negative sentiments are displayed as Red tweets, happy tweets are Blue.

The whole thing is built on node.js using node-tweet-stream, node-sentiment and socket.io. The frontend map is leaflet with stamen design's Toner tiles.

It's quite fun to watch, especially when there's a football match or a concert. If you click on the "follow tweets" checkbox, new tweets pop up as they arrive, although currently that makes the map pan north.

Thanks!

Dario.

Very nice. It also gives me the impression that people in the West End are certainly more angry (or have free time to be angry on twitter) during office hours than those in the City.
