Cool Screen Backgrounds Using SAS Graph

In this paper, we show how the SAS Data Step Graphics Interface (DSGI) can be used to generate graphics files which can be used as unusual and interesting screen backgrounds for web pages. We begin with patterns of tessellating polyominoes. (A tessellation is a tiling of the plane. A polyomino is like a domino only bigger i.e. it is made up of more than two squares.) Later we move on to squaring the square patterns, and show how to incorporate images into them.
