Hatnote has created a very cool, and impossibly addictive, audio/visual representation of everything that takes place on Wikipedia. Every time an entry is edited a tone is played and a circle splashes on the screen. Bell sounds are additions to an entry and string sounds are subtractions. The size of the circle represents how big the edit being made was.
This map listens to live feeds of Wikipedia revisions, broadcast using wikimon. We built the map using a few nice libraries and services, including d3, DataMaps, and freegeoip.net. This project was inspired by WikipediaVision’s (almost) real-time edit visualization.
Listen to Wikipedia was written by Stephen LaPorte and Mahmoud Hashemi, and is open-source. Like RCMap, L2W gets its real-time Wikipedia data as broadcast by Wikimon. L2W was inspired by and partially based on Listen to Bitcoin, but was mostly rebuilt to use D3.js (also like RCMap). We also use howler.js for cross-browser audio support, and additional sound processing was facilitated by SoX.
