  We propose a simple dynamical model of the glass transition based on the
results from a non-randomly frustrated spin model which is known to form a
glassy state below a characteristic quench temperature. The model is
characterized by a multi-valleyed free-energy surface which is modulated by an
overall curvature. The transition associated with the vanishing of this overall
curvature is reminiscent of the glass transition. In particular, the
frequency-dependent response evolves from a Debye relaxation peak to a function
whose high-frequency behavior is characterized by a non-trivial power law. We
present both an analytical form for the response function and numerical results
from Langevin simulations.
