I was a militant smoker, and in my case, I think I particularly used smoking because what I felt was a kind of politically correct big brother assault on smoking.
Personally, I've found that the kind of thing that I like is going into somebody else's area and not playing their music but doing whatever I do in their area.
Realizing this, I knew that the actual space of a room could be broken down and played with by planting illusions of real light (electric light) at crucial junctures in the room's composition.
