Fart Radar

If you're in a group of friends and suddenly something stinks, you're going to want to find out who's responsible. You could stage a kind of police interrogation and wait for someone to confess to the crime, or you could just use Fart Radar.

This app will activate a 'radar' that can detect the person who farted shamelessly in front of everyone in the group.

Once it finds the guilty party, the Fart Radar compass points, with an arrow, in the original direction from which the gas was produced.

Obviously this program is a game with no scientific basis for actually finding out who's made natural use of their bodies, as they are perfectly entitled to do. But it's still good for a laugh and maybe playing a joke or two with the kids in the family.
