Listen to Wikipedia by Stephen LaPorte and Mahmoud Hashemi
Listen to Wikipedia is a visualization and sonification of Wikipedia's live recent changes data. The sounds indicate addition to (bells) or subtraction from (strings) a Wikipedia articles, and the pitch is inversely proportional to the size of the edit (a lower pitch means a bigger edit). Green circles show edits from unregistered contributors, and purple circles mark edits performed by automated bots. A string swell welcomes a new user to the site. There's something reassuring about knowing that every user makes a noise, every edit has a voice in the roar. Now, let's go make some noise.
