a roundabout light installation consisting of a 6 meter high internally lit, traffic tower & a UFO platform made of a smooth concrete plate with a light green reflecting, artificial coating. in the middle of this, a big red letter 'U' (for UFO). the light in the tower changes its color as soon as traffic on the highway has low intensity. then the UFOs will know that they can start their landing. the intermediate 300 meters are lit with blue lights on both sides of the road, much like one sees at airports. see also litmus.
