College Artworks

Yesterday when I attended classes I visited the college art gallery during the break. A mixed media exhibition is going on over there which has some bold looking artworks that perhaps would fit only a gallery and would never grace anyone's home. I wonder what the artist had in mind while creating these works of art. I personally didn't understand the art and there was no explanation signage to help me understand. All I can say is there are a variety of objects used to create something attractive.
