Please do! Are we talking about Microsoft Bob or what?

While I was there they were working on integrating presence detection. I saw some demos where lights would go on and off when you walked from room to room, and music you were listening to would follow you. If you were using a computer your desktop environment would migrate to a computer in the new room. Never saw that hit the market in any way I was aware of.

Lots of stuff MS Research did never saw the light of day. One time when my kids were playing Toontown I found a bug that let a player slip behind the graphics. You could see that the clerk at the store was just a legless torso floating in the air, and you could even go behind the walls and fly backwards into empty space until the whole world shrank to a dot. This same bug was present in a MS project called V-Worlds I had worked on a couple years earlier, so I always wondered if they had made a deal with Disney to use the code or if it was just a common graphics bug.
