  Using controlled spinodal decomposition, we have created a fluid-bicontinuous
structure stabilized by colloidal particles. We present confocal microscopy
studies of these structures and their variation with kinetic pathway. Our
studies reveal a rigid multilayer of colloidal particles jammed at the
interface which prevents the liquids demixing for many hours. The arrangement
of two-fluid domains, interpenetrating on the meso-scale, could be useful as a
microreaction medium.
