JavaScript Song Player

http://sk89q.therisenrealm.com/2008/11/dynamically-generating-a-wav-in-javascript/

This plays a song by generating (many) .wav files on-the-fly and playing them all through an EMBED tag linked by a data URI. No external files are used to play the song. You can save the source of this page and it will work anywhere you try it. Due to the length limit of data: URIs, multiple .wav files are used.

This has been tested to work on Firefox, Opera, Safari, and Chrome.
You need to have a plugin to play the .wav files, and it must support "auto-play."
If it doesn't work, try the simple sine wave generator. If that does not work either, you do not have the proper plugins.
