In 1999 there was a world war, the “Holocaust”. London was obviously badly hit as Dominick tells his friends to be out of the city by then.
Commring - a ring sized communications device, both for person to person and person to computer calls. Dominic
uses it to talk to SOO (qv) to check on what is happening at his house.
A wall of the living room is taken up by a multi=purpose screen that works
as a 2D video screen for phone conversations and as a 3D projector for
entertainment use.
SOO is the household computer. It can talk to the occupants, and over comms links.
It can scan objects in the house and appears to acts as a complete house
manager come secretary.
Wide brimmed hats because of the UV
Open relationships but no “cheating”
We are only really given a good look at Dominick's house. It is very “2001” ish,
modernist and minimalist. Dominick remarks on the clutter in Jane's house, and also comments
on how sterile - physically, emotionally and biologically his life is.
There is some sort of sonic shower and dry in one scene.
Caleb's office/house is similarly modernist, if richer in colour and decoration.
Apart from the saucers the only transport shown is their equivalent of the London Undergound,
some form of suitably quiet and plush mass transit system.
