  We investigate the equidistribution of Hecke eigenforms on sets that are
shrinking towards infinity. We show that at scales finer than the Planck scale
they do not equidistribute while at scales more coarse than the Planck scale
they equidistribute on a full density subsequence of eigenforms. On a suitable
set of test functions we compute the variance showing interesting transition
behavior at half the Planck scale.
