A while back I posted a link to my morse music page:http://www.cognimetric.com/acrawford/codemusic
I've been playing around a little more and come up with a page which lets you generate a "musical morse" MP3 file from a phrase of your choice.
As far as I can tell this has no practical use whatsoever - it certainly wouldn't be legal to send over the amateur bands - but life would be boring if everything had to be useful, right?
The tunefulness of the results rather depends on what phrase you give it to "send". If you'd like to play, head on over to:http://www.cognimetric.com/acrawford/page/morsemaker
