Peter sez, "The One Laptop Per Child project's sonic contributors have been hard at work. They've collected 8.5 GB of Creative Commons-licensed sounds from the likes of the Berklee College of Music and electronic superstar BT. These are free for use whether or not you've got an OLPC. They've also been working on musical applications for children using the machines, building on Csound, an open-source synthesis and effects tool. The upshot: open music development on the OLPC will benefit the whole music community, not just XO laptop owners."
