1. A configurable transparent structure comprising:

  • a light source;

    a transparent light-carrying layer optically coupled with the light source; and

    a light extraction layer optically coupled with the transparent light-carrying layer, the light extraction layer being operable in a first state, in which light emitted by the light source passes through the light extraction layer without scattering such that the light extraction layer appears substantially transparent, and a second state, in which a portion of the light emitted by the light source is scattered upon passing through the light extraction layer, such that the light extraction layer appears at least partially translucent.
