In the game "Space Colony", when a colonist would claim a bed, it would change the bed graphic.
I think something similar to that would be cool to see; when someone claims it, it simply changes to a different graphic.
For example, a colonist claims a bed, it changes to a pink blanket with stars on it. I imagine the code would be simple enough and there's almost an endless amount of different kind of visuals. Maybe just a bed with the blanket kind of pulled down; maybe a bed that hasn't been made. Maybe a bed with simply a different color pillow, ect. combine that with how many different blanket designs you could imagine, and bamn, instant, simple variety.
