We argue that the low energy electron excitations of the curved graphene sheet $\Sigma$ are solutions of the massless Dirac equation on a 2+1 dimensional ultra-static metric on ${\Bbb R} \times \Sigma$. An externally applied magnetic field on the graphene sheet induces a gauge potential on the world volume of the membrane which could be mimicked by considering a stationary optical metric of the Zermelo form, which is conformal to the BTZ black hole when the sheet has a constant negative curvature. We show that there is fundamental geometric obstacle to obtain a model that extends all the way to the black hole horizon.
