Also notice that, because the variable RE is set to one, this pattern
repeats only once.
Now’s the time to experiment with some of your own changes to the
variables and loops.
Summary
In this chapter you used a single string of ones and zeros to create a
two-dimensional figure. You can use this technique to create large pat-
terns with little drain on computer memory, but only with highly
structured patterns.
You also used a graphics density of
72
dots per inch to produce a
one-to-one aspect ratio of the dots.
