No matter what time it is, there are people all over the world joining, contributing, and editing Wikipedia. At 4AM local time, there were 49 edits per minute. Listen to Wikipedia monitors that activity and renders it as a data visualization with sound.
Listen to the sound of Wikipedia’s recent changes feed. Bells indicate additions and string plucks indicate subtractions. Pitch changes according to the size of the edit; the larger the edit, the deeper the note. Green circles show edits from unregistered contributors, and purple circles mark edits performed by automated bots. You may see announcements for new users as they join the site, punctuated by a string swell. You can welcome him or her by clicking the blue banner and adding a note on their talk page.
Click on the circles as they appear to go to the page that are being edited and see what changes are being made. You can also scroll down on the page to filter the data by type or by language. Even if you aren’t sucked into exploring the world of Wikipedia edits, the plucks and chimes are quite soothing to listen to as you do something else.
