Art is very expressive, and is a very old form of art. There are many diferrent types of art, but two major ones are abstract and representational.
Abstract art is very interesting. It means that when someone looks at it, they don't say,"Oh! It is a car!" or, " It is definatly Mike Weir." The artist uses line, shape and colour to express the mood they want to send out.
Representational art is art that represents something like a car or Mike Weir. It is just as interesting as abstract art.
