  We investigate a strong coupling expansion of N=6 superconformal Chern-Simons
theory obtained from the semiclassical analysis of low energy, effective
degrees of freedom given by the eigenvalues of a certain matrix model. We show
how the orbifolded sphere S^7/Z_k of the dual geometry emerges dynamically from
the distribution of the eigenvalues. As a test of this approach we compute the
energy of off-diagonal excitations, finding perfect agreement with the
dispersion relation of giant magnons.
