Yes, you read that correctly. You can LISTEN TO WIKIPEDIA. If I really needed another reason to love Wikipedia, this is it. This project built by Hatnote applies sound to 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."
I find the whole experience to be both a relaxing Zen experience and irresistibly compelling at the same time. It really shows how dynamic Wikipedia is. I have found myself putting this on as background white noise while I am working.
You might display this using a projector in your classroom to see what sparks interest and curiosity. Listen to Wikipedia can definitely open up some new rabbit holes to explore.
NOTE: I have found that this works best with Google Chrome as the sound does not play when using Safari. Check it out for yourself at http://listen.hatnote.com
