Living in a shopping mall: How to not go crazy in a space habitat
One of the common arguments I hear about Why We Shouldn't Live In Space is, we'd go mad spending all our lives in an artificial environment. And there's some validity to that; we evolved in forests and open plains, running wild and unfettered, Booooorn freeeee, as free as the wiiiiind
Ahem. Sorry.
The point is, we need to have some relief from obviously manmade structures every once in a while, or there are real psychological effects. There have to be ways to mitigate these issues and prevent any resulting social difficulties.
The most obvious of these fixes is, fake sky. A visual representation as realistic as possible, bright and blue and seemingly open, with natural looking sunny rays, cloud illusions giving slight changes in brightness and light angles throughout the daylight hours. Night is easier, it's just darkness with stars. But to look up and see only a roof and artificial lighting, wears on a body after a few years or decades. It's like being in an inescapable casino.
Also needed are green parks, with trees and grass and rocks. Fractal mapping can create natural looking landscapes with hills and small valleys that are visually and audially isolated from outside structures and visibly artificial features. Care must be taken not to have too many people in the park at once, allowing for the illusion of being alone or in isolated groups in the "wilderness" areas. Of course, sometimes you want more people around, picnics and parties and dances in a lush setting.
Even the "city" areas will need open spaces to avoid conditioning children to agoraphobia. These will need to be planned as much as the green spaces, and in concert with the sky images.
