  We recall the directed graph of _juggling states_, closed walks within which
give juggling patterns, as studied by Ron Graham in [w/Chung, w/Butler].
Various random walks in this graph have been studied before by several authors,
and their equilibrium distributions computed. We motivate a random walk on the
reverse graph (and an enrichment thereof) from a very classical linear algebra
problem, leading to a particularly simple equilibrium: a Boltzmann distribution
closely related to the Poincar\'e series of the b-Grassmannian in
infinite-dimensional space.
  We determine the most likely asymptotic state in the limit of many balls,
where in the limit the probability of a 0-throw is kept fixed.
