To be honest, an engine block wouldn't look out of place in my living room. :)
I don't have a living room..... I do have a 'large machine room' which the
owners of the house called a 'living room'
 Both the room and the machines I am going to set up in there are large.
I realised the other day that I do not live in a normal house. Apart from the toilet,
every room on the ground floor contains at least one PDP11 (some not set up yet).
