Psst... Seizing Attention

Sonic targeting, using speakers mounted above the billboard, the system projects an isolated beam of sound down onto a targeted area of the sidewalk drawing the passerby's attention to the billboard. Outside of the specific targeted zone, all you will here is silence (insofar as that is possible in NYC). In the pictured example using technology from Holosonics, a women's voice whispers, "Who's that? Who's There? ...It's not your imagination." Pedestrians entering the beam hear the chilling message very clearly. OK, it's a bit intrusive, but at least it's fun...
