Pendulum Wave Music Machine 2

OK, I managed to make a bigger (2 octave) version of this:

Previously I thought this would not be possible because it seemed to require a width of 5 studs per hammer, which would make it much too wide for the glockenspiel.  However, I managed to find a way to reduce it to 4 studs by sneaking two differentials in next to each other.  (With LEGO there's always a way!)  The reduced width also required a different hammer actuation mechanism.  The whole design has also ended up much more rational and robust.

I can see this being so fascinating at a brick convention but also so bloody annoying too...
