  We review some recent work and techniques for constructing dynamical string
solutions in AdS spacetime. These solutions generalize the folded string and
multi-spike solutions of GKP and Kruczenski. The methods developed for
constructing these dynamical solutions are based on Pohlmeyer reduction to
integrable sinh-Gordon type equations. The integrability of the equations is
seen as the crucial tool for reconstruction of the string configurations. We
discuss the physical meaning of these dynamical spike solutions and the
question of their moduli space.
