You can obviously do soooo much with it, that my mind boggles. As an example of how much more you can do versus some other things, I can only contribute a very boring example (involving no musical universe at all) via "Linux on the Web":

    1) Goto http://lotw.site/shell
    2) At the prompt, enter : import av && beep
    3) Once your head starts pounding, hit Ctrl+c

Now wasn't that boring! :)
