This is why I ask, while looking for a tree macro I came upon this page:

http://www.netaxs.com/~ptdawson/ptdtree3.htm

which has a picture with a thousand trees and says that it only takes up the
same amount of memory as one tree. Is this because they're made up of
triangles and not other objects?
