Inside Bill Gates' Home

http://science.howstuffworks.com/smart-home.htm Microsoft Chairman Bill Gates' home just outside of Seattle, Washington, might be the most famous smart home to date. Everyone in the home is pinned with an electronic tracking chip. As you move through the rooms, lights come on ahead of you and fade behind you. Your favorite songs will follow you throughout the house, as will whatever you're watching on television. You can entertain yourself by looking at Gates' extensive electronic collection of still images, all available on demand. The chip keeps track of all that you do and makes adjustments as it learns your preferences. When two different chips enter the same room, the system tries to compromise on something that both people will like.
