Given a sequence $f_j$ of analytic maps of the open unit disc $\mathbb{D}$ into itself, we consider conditions that guarantee that the sequence $f_1\circ\cdots\circ f_n$ of compositions converges uniformly on $\mathbb{D}$ to a constant. The proofs are given entirely in terms of two and three-dimensional hyperbolic geometry. Keywords: Continued fractions, M\"obius maps, hyperbolic geometry, angular derivatives.
