Something we need: Refrigerator Alert System

And this is how it works: Every day, early in the morning, an electronic brain in the refrigerator takes stock of things inside that haven't been touched for at least a week. And then it transmits a message to a marquee on the front of the refrigerator door, blinking in red letters as you walk past: "Cottage Cheese! Remember you have cottage cheese in here. Mmmmmm. How about some cottage cheese with sliced peaches? Doesn't that sound good?"

And you think, "Hey! I'd forgotten all about that cottage cheese." Because how many times do we buy something and forget that we've bought it, and it lingers there in some dark corner, behind the pickles and olives and cabbage?
