text: As people ride bike or hike or even just walk around their city, they can see and learn many new things just by being more aware of their surroundings. Cars have been in this world for a long period of time already. It's time to take a break from the madness and start realizing how beautiful life is and how beautiful it can be by not destroying it with such a machine. Not only will there be less stress, but the world will be a lot more safer than it was.    In the article "Making Mona Lisa Smile", it talks about a new technology that enables computers to identify human emotions. The new technology is called Facial Action Coding System. At the very beginning of the article, it talks about the emtions of Mona Lisa for she is eighty-nine percetnhappy, nine percent disgusted, six percent fearful and two percent angry. Honestly, if I was forced to sit for hours and stare at nothing while some old guy painted my picture, I would not be very happy about it. The technology works by constructing a 3-D computer model of the face that it has been presented with all 44 major muscles in the model must move like human muscles. Dr. Paul Eckman, the creator of FACS (Facial Action Coding SYstem) has classified six basic emotions-happiness, surprise, anger, disgust, fear and sadness.
