Inspired by Julius Neubronner military/spy application where pigeons were used to take photos during flight, Pigeonblog uses homing pigeons, equipped with a custom built air pollution sensing device to report air pollution. The data is visualised using Google's mapping environment.   A documentation of the Pigeonblog was shown at Unsafe Distance.
