Product idea 1: A program you can install on your computer that locks up the computer every now and then, and the only way to unlock it is to smile at the webcam. That way, you'll smile at least a few times a day.

Product idea 2: Competitive smiling. Your laptop's webcam monitors your face for smiles, records the total amount of time you smiled each day and sends that data to a website, so that you can compete with your friends from all over the world. World's longest-duration smiler wins the Dalai Lama Award, unless you are actually the Dalai Lama, in which case, you'll win the Happy Llama Award.
