Abstract
An apparatus, including: a light source; a controller configured, in response to the occurrence of a first event involving the apparatus, to control the light source to produce a first, time-varying, illuminative effect that varies between maxima and minima of illumination intensity over a period of time following the occurrence of the first event, wherein the variation in the first illuminative effect is indicative to a user that the first event has occurred; and the controller being further configured, in response to the occurrence of a second event involving the apparatus, to control the light source to produce a second, time-varying, illuminative effect that varies between maxima and minima of illumination intensity over a period of time following the occurrence of the second event, wherein the variation in the second illuminative effect is indicative to a user that the second event has occurred.
