Work no227 "The lights on and off"

I don't know if I do understand what it means this piece of art work.
When I heard martin talked about his work, suddenly, I feel life is that you don’t know what to do in between; it’s so limited, too limited, really limited, and absolutely limited!!!!!!!!!

I think if an art work let you have some kind of reflection, it's good already.
