#38. 3D Sonar Computer
As Seen In: The Dark Knight (2008)
Yes, using the 3D sonar machine Lucious Fox built would be a major invasion of privacy if ever used, but I'm sure we could find at least one good use for it. Using mobile phone signals to map out locations and pinpoint certain conversations is effing genius. It may have been too much power for on man to handle, but maybe the government could use it to find Osama, or whoever shot Biggie and Tupac.
