I thought part of the problem with force-feedback was concern for the
safety of the user.  Mechanical devices are bulky and could possibly
pinch the user in undesirable ways, and the fluids you speak of intro-
duce the problem of more electricity that could possibly shock the
user.  What interested me was a report of some sort of gelatinous 
substance that contracted in the presence of visible light, reported
in the Wall Street Journal on or around 8/17/90.  Would it be feasible
to construct an exo-muscular system into a data glove or a body suit?
