People's Architecture Office created this tubular (in the literal and the Teenage Mutant Ninja Turtles sense of the word) installation in Lane Crawford retail locations in Beijing, Shanghai, and Hong Kong to show what it would be like if we all lived in tubes. And it looks like it would be...a little cramped. But also theoretically possible. And also very shiny, so that's nice.
