  The dynamical equations describing the evolution of a self-gravitating fluid
can be rewritten in the form of a Schrodinger equation coupled to a Poisson
equation determining the gravitational potential. This approach has a number of
interesting features, many of which were pointed out in a seminal paper by
Widrow & Kaiser (1993). In particular we show that this approach yields an
elegant reformulation of an idea due to Jones (1999) concerning the origin of
lognormal intermittency in the galaxy distribution.
