Bill Gates' house outside of Seattle is tricked-out techie-style. Each guest/resident is given a chip that maintains their preferred temperature setting in every room they enter and other personalized options. There are also speakers in every room, hidden behind wall paper, so, as you walk from room to room, the music follows you. Inside the 30-car garage, you'll find a custom Porsche 959 Coupe, which required Bill Clinton to sign a special law so Gates could drive the sportster with questionable emissions and unknown crash ratings. All in all, the home is a modern marvel and it's speculated that the Microsoft pad was designed on Apple computers.
