Customizable Condo Enviroment

What if you could change the enviroment around your house.
Such as the Skybox lighting, time of day, ect. (sort of like the g-mod enviroment changers)
Would be really cool if it could be implemented.
Ideas to addon to this would be appreciated.

A similar thread has been made, but it talked about the whole condos instead of the time of day.

I am very sure this is already planned to be added. Although I thought about skybox texture (was it that one?).
Would be cool nevertheless.
