Graphical objects are instanced by assigning a new identifier to a class name. For example,
a = Cone; b = AsciiText
where the `;' is required only if two commands are to be specified on the same line.
Objects of user-defined classes are actually references to a single scene graph read locally from a file or over the net from a URL. These graphs could be very large such as a high resolution model of a building or a city block.
The AsciiText class requires that you assign its string attribute to the actual text you want to display.
b.string = "something to say"
