In this talk I will
discuss a cosmological model where primordial inflation is driven by a `solid',
defined as a system of three derivatively coupled scalar fields obeying certain
symmetries and spontaneously breaking a certain subgroup of these. The symmetry
breaking pattern differs drastically from that of standard inflationary models:
time translations are unbroken. This prevents our model from fitting into the
standard effective field theory description of adiabatic perturbations. Consequently,
it exhibits a novel non-Gaussian `shape'.
