This question has been often debated at my house. I like looking at well done graffiti. I enjoy thinking about graffiti on trains. The pairing of this art form (meant to be temporary and fleeting) painted on trains that move through time and space with their roving art exhibits can often be quite spectacular! nd yet, graffiti is often done in an illegal, defacing manner that is obviously, hard to support wholeheartedly.
You might open this discussion in your house by watching this video with your kids. There is much to talk about. The end project is striking in its beauty; the means to the end may be objectionable. What do your kids think?
