text: The thing about it is who was the person to come up with this idea I think its cool but there using up all this technology. I think that there is a reason for everything and I wonder what made that that person come up with that idea. Another reason why I think this is a cool idea is because it knows who you are even when you have on different face expression. That's amazing how a computer can express how we feel .I 'm so surprized that a computer can do that. I some time ask myself how do they do that.
