This video is a great example of taking something that on it's own doesn't mean much, and turning it into art. Using sounds from an operating system (in this instance, Windows XP and 98) and creating a piece of music from it really shows that you can make something from nothing. There are other versions that have been created using Mac OS and other Windows operating systems, but in my opinion this is the best one.
Lawrence Lessig is an academic in favour of free culture. Lessig's view is that having the freedom to freely modify and distribute works is the only way to promote creativity, as opposed to copyright laws which hinder it. One example of this is Creative Commons, which was founded by Lessig. This particular video created by people at American University focuses on fair use. Fair use permits use of copyrighted material without having to gain permission from the author/rights holder first. There are many different ways of using fair use, including for teaching, commentary and research. One thing that is important regarding fair use, is giving credit to the author/rights holder.

Fair use is important for creativity. It allows people to share and build upon existing works legally, as opposed to stifling this with copyright laws that essentially prevent anyone from doing anything other than looking at the work.
