Hmmmm...this could be interesting - it depends on the timing of those photos!

Let's say you leave a delicious treat in the fridge, with instructions that nobody is to touch - it's for later. Yet, you come home to find that somebody has been eating it.

Your fridge camera could catch the guilty party red-handed (as long as everybody's hands don't look identical, that is).

As for it's main use, I'm not sure it would help me much. When I'm going shopping, I just look at what we need, remember when I get to the shops and stop myself buying the things we already have, or don't need (like milk, cheese, or eggs.

Maybe another case of adding tech/gadgets to your life just for the sake of it?

Nice hunting, though :)
