That's fine.  I'm still in the "alarming cats" stage myself. :-)

I think it would be very interesting to see a 3D plot of the capacitance 
field of the theremin, with those tuning setting superimposed on it.  I 
envision the field to be like a big cylinder, but I would assume the 
field is rounded on both ends?  Or is fatter around?
