Composition of Generative Art

In this chapter we'll explore techniques from generative art, which will in turn allow us to explore key concepts for functional programming. We'll see:

• uses for map and flatMap that go beyond manipulating collections of data that we've seen in the previous chapters;
• how we can handle side effects without breaking substitution; and
• some interesting, and possibly beautiful, images that combine elements of structure and randomness.
