In the words of the Conchords, a team of Canadian students just wanted to do something special for the lay-deez of the world. And so they came up with the Ladybag concept. It's a smart bag that uses RFID technology to ensure that you leave the house with those three staples you need in the modern world: mobile; keys; and wallet.

Developed by a team at Canada's Simon Fraser University, the bag, which uses RFID technology, also has LED icons on the side, which illuminate when the bag is missing an object, while a smiley emoticon lights up when you're ready to go. I think they left off the lipstick icon, though. [Ladybag via Talk2MyShirt]
