A pair of linked decorative objects that come in a variety of styles. The objects show activity from a remote location. If one light senses nearby sounds or movement it tells the other light in the other house to turn on. More activity makes the light brighter. A user’s presence is communicated to others only if he/she explicitly activates the IPL device.
Concept that is later based on this idea: Intentional Presence Lampshade
