  We give four applications of Zalcman's lemma to the dynamics of rational maps
on the Riemann sphere: a parameter analogue of a proof of the density of
repelling cycles in the Julia sets;similarity between the Mandelbrot set and
the Julia sets; a construction of the Lyubich-Minsky lamination and its
variant; and a unified characterization of conical points by Lyubich-Minsky and
those by Martin-Mayer.
