Kickstarter: Game of Phones.
One player picks a card and gets to judge that round. They read the prompt to everyone else. Something like 'Find the best #selfie' or 'Show the last photo you took'. Everyone finds something on their phones and shows the judge, who gets to choose a winner for that round. First to win 10 rounds is the overall winner.
Can't decide if genius or lame.
this definitely does not need to be a physical product. it could easily be an app and would be much more successful/sensible.
