It's 'self-published', which is of course a polite way of 
saying it is duplicated and bound at a copy shop.  :)

In brief, it's a collection of fairly simple stereo hacking 
projects.  The simplest is the hyperstereo sliderule 
calculator (you just copy the page onto card stock, snip it 
out and assemble).  Although that chapter is full of all 
kinds of semi-painful mathmatical explanations about why it 
works.  The Q-DOS-like lens is probably the next simplest.  
I thought the results were somewhat interesting.  As the 
previous poster pointed out, the stereo effect is limited 
to the ranges that are OUT of the depth of field for that 
f-stop.  Quite frankly however, that's just a function of 
it being a very cheap and cheezy conversion of a normal 
lens.  If one could convert the lens so it had two separate 
(filtered) apetures, that wouldn't be the case.

The meat of the booklet however are the chapter on 
twinning XA-2 cameras (either wired or wireless versions) 
and the chapter on building a siamese twin stereo camera 
out of a pair of Argus C3s.  I suspect that's the reason 
95% of people pick up the thing.  They're both fairly 
simple projects.  Especially the wireless version of the 
XA-2 rig.  That was something I'd wanted to do for quite 
some time and I'm very happy with the approach.  It has a 
certain simplicity to it I find very attractive.
