There was this one program I used a lot back in the day; I'm pretty sure it was called Virtual Places.
Basically it was a browser that turned any web page into a chat room, and you could chat with anybody browsing the same page. Everybody would have these little square avatars; mine was an eyeball. And you could get a bunch of people on this little "bus" that somebody could "drive" and all move to a different web site together.
