  A very cool project called SkyEar, which is a cluster of helium balloons with on-board electronics to monitor local wireless-band radiation. The balloons have LEDs that light up in different colors, depending on the signals they find.

  Basically: Stand near it, make a cell phone call, it changes color, demonstrating the ‘local hertzian culture.’
