This article discusses the relationship between art and morality....how far can you go in the media, in the name of art, without becoming immoral?

c.f. these words from Humanae Vitae (no. 22):

Everything in the modern means of social communication which arouses men's baser passions and encourages low moral standards, as well as every obscenity in the written word and every form of indecency on the stage and screen, should be condemned publicly and unanimously by all those who have at heart the advance of civilization and the safeguarding of the outstanding values of the human spirit. It is quite absurd to defend this kind of depravity in the name of art or culture 

Jesus, you who said to avoid lustful gazing, please help our our world
have a great love for wholesome art
