Spün counts calories in each bite and vibrates when you've had enough

This smart cutlery could be a dieter's worst nightmare, or the weight loss tool you've been dreaming about. Spün claims to be the world's most intelligent utensil, using a combination of image recognition and motion sensing technology to measure food as users eat it. The device, which has an interchangeable stainless steel spoon or fork head, weighs each mouthful of food to calculate the calories and nutrients being eaten.
