Self Stirring Mug

So how often are you somewhere you have a tea bag, hot water, a glass, sugar cubes.....but not a spoon?

"It debuted recently at the London Design Festival. It was designed by two Frenchmen who were out to make a cup for hot beverages that wouldn't need a spoon. You can see in the picture that the bottom of the cup sticks out and there is a ball in that part. All you have to do is gently swirl the cup a bit to get the ball moving, and that motion is what stirs the contents of the cup."
