I do belive you mean Bill G's Machine'S look like. He probably just has a bunch of media computers. A friend of my dad was an engineer for microsoft, and apparently (this could be false information but my dad counts him as reliable) bill gates has some sord of high defenition screen all over his house, and depending on what he feels like, he can change the settings of his house (or some parts of it) depending on his mood. I.E the wallpaper, art on the wall. Even if this isnt true its a good concept.
