1. A lighting device for creating dynamic atmospheres, said lighting device comprising:

  • a light source adapted to operate in a plurality of color states, the light source emitting differing colors for each color state;

    a random generator;

    a controller for controlling the color state of the light source, the controller adapted to provide a transition between a previous and a subsequent color state based on a output provided by the random generator;

    a stochastic model defining transitions between subsequent states is implemented in the controller;

    wherein the controller is adapted to provide the transition between a previous and a subsequent color state such that, based on the outcome of the random generator and starting from a present color state, the controller is arranged to decide and control by the stochastic model which subsequent color state is realized based on the present color state;

    a multimedial output device driven by multimedial sources;

    a clustering circuit for clustering the multimedial output according to a predefined aspect;

    a computational circuit for computing a statistic on subsequent transitions between the clusters of the multimedial sources;

    a processing circuit for generating probability parameters associated with the computed statistic; and

    an output circuit for outputting the probability parameters to the random generator so as to implement the stochastic model.
