Recently, they’ve begun manufacturing toys that can to alimited extent read your brainwaves. They can be programmed to act accordingly. I think a really -knock-out- idea would be to combine this technology with a mobile device such as the i-Pod. Someone could keep plugged in and the device would change the music to match their mood as they went through the day. It could be programmed with sounds and lots of other stuff, too. Life really -could- start coming with mood music like in the movies… 🙂 It can also be used to manipulate the expressions of an avatar during online chats. Many, MANY possibilities. What do you think?
