Gneutronica?

[D. Michael McIntyre]

Nobody had heard of mScore before I mentioned it, so I thought I'd toss this 
one out too.  I just ran across this, and haven't built or looked at it, but 
it seems interesting (especially to you GNOME devotees) and doesn't seem to 
have been packaged yet:

(This is not an official endorsement, since I haven't built it, and have no 
idea how usable or intersting it might prove to be.  The build instructions 
look too complicated for me to fool with just now, and since it's a GNOME 
app, I probably wouldn't like it anyway.  :)  )
