Meredith,

We certainly don't want to be accused of torture, though we'll gladly plead 
guilty to some discreet teasing.

For a little more tease, 
see   http://bnordgren.org/seismo/FBVert01.zip    a photo and a couple of 
sketches.  The photo shows a slightly earlier configuration, but is 
basically what Dave is running now.

We want to go slowly in regards to encouraging folks to start trying to 
make something like this until we feel we're able to do our part to help 
with any problems.  Building one of these would definitely not be a good 
first project, though I think we are coming to the point where we can 
provide some more detail if there is any particular interest.

Regards,
Brett
