Is there a way to make an audible noise when a computation is complete?

edit

You can try this on any new browser.

def done():
    return html('!audio src="http://www.radokirov.com/gong.ogg" autoplay> Your browser does not support the audio element. !/audio>')

for i in range(10**6):
    pass
done()

Replace ! with < . I could not make the code display otherwise.

In the future a function "done()" along with a sound file can be a part of the notebook. I will remove the .ogg file from my server in the future to prevent too much hotlinking (so don't freak out if this doesn't work).

I added gong.ogg to my notebook, so I can serve it locally. It took a while, but I finally determined the path to the image files:

<$SAGE_ROOT>/local/lib/python2.6/site-packages/sagenb-0.8.2-py2.6.egg/sagenb/data/sage/images/gong.ogg

The URI to the file is:

http://localhost:8000/images/gong.ogg

The file plays fine in Firefox; guess Safari doesn't know how to play an ogg file.
