I suppose art of this nature is not meant to be "pretty" or beautiful, but rather to make the viewer think in a different way. Understanding a bit about what the artist was trying to convey might make you appreciate them in a different way, but you still might not want to put them in your living room. I had a university art history lecturer once say, "You don't have to like an art piece to appreciate it." Having said all that, I'm really not sure what this artist was trying to say.
