     Good stuff ... but it is, what would you call it ... 'active',

 Obviously you need to sign up for Fluid Dynamics 201.
 

    Some kind of light oil may have been the better choice ... but not
    TOO thick.

 You must have skipped the article. When you're talking about a system
where 1 is represented by a vacuum and 0 as atmospheric pressure, you're
not talking about light oil.

   Vac or not ... sounds more like 'gas' stuff  :-)
   "Fluidic elements" - posted maybe by you - seem to
   involve a tiny flow chamber where you can form one
   or another kind of vortex. One spiral yields '1's,
   the other '0-s', on the output port. Interesting.
   There are, of course, other ways to do 'hydraulic logic'.
   However the 'no valves/pistons/etc' trick seems extra cool.
   STILL wondering what might be done with non-Newtonian
   fluids .......... VELOCITY becomes part of the
   design equation. Think (do they have it where you
   are ?) "Silly Putty". Flows like a fluid if you
   leave it sit, but seriously hardens-up if you try
   to shape it suddenly. Some water/starch mixes act
   the same.
