What I now know

A representational sculpture is one that is supposed to represent a real life object.  For example, the sculpture i saw in New York City of the metal trees was a representational sculpture because it was created to look just like a real tree.  An abstract sculpture is a sculpture which was created not to look like anything in particular, but could look like something to different people.  In order to create a found object sculpture, i would see what found objects i had to work with, and think of something in my head which i wanted to create.  I would then start getting pieces together until finally i knew what i was going to do.
