Not just a proto. There were commercial models (other marks, Saab among them, i think, or Volvo) with LC-based window tinting. Also, a lot of cars today use LC's to auto-tint the central rear-view mirror when someone driving behind you hits it with high beams.

There were also some house windows mentioned installed somewhere (again, can't remember where ) and i recall reading about a prototype window containing both, a transparent photovoltaic layer and an LC layer, sandwiched between the glass panes.

On a side note, transparent e-paper could create some interesting new possibilities for user interfaces... Stacking sheets with annotation on sheets with content, for example (in a "dumb" way, like overhead transparencies, or with some imbued "intelligence", i.e. sheets "sensing" one another's content and position).
