We present experimental results on bistable elements with liquid crystals as nonlinear elements showing that, under cw illumination, sequences of spatial structures occur. Index fluctuations, as a particular characteristic of this class of material, seem to play a central role in this effect. We describe the system and discuss some of its key properties.
