The (fake) metal detector for your next cops and robbers party.
A "not allowed" image appears gradually and a sound can be heard when you reach the horizontal holding position of the iPhone or iPod touch while "wanding" a person with it.
(With a bit of practice you can determine where the "contraband" seems to be hidden.)
The horizontal holding position can be calibrated and left-handed usage (the home button shows to the holding hand) or right-handed usage (home button shows away from hand)
can be set in an option-screen.
An intensity-meter shows the detection strength of the hidden object as a value from 0 to 100 (percent).
under usual conditions it is sufficient to connect earphones to the iPod Touch in order to hear the sound
in the vicinity of the device, but in a louder environment external speakers are recommended.
