What other kind of objects are out there? Let's take a look. Here's where the optional section takes you on a tour of things to come. Combine this with a tester program and enjoy: it's not as easy or straightforward as in BSL/ISL+ but it's real, and genuine graphics programming. We learn about a few more graphic tools as we put together this drawing (set up and run through this tester program). Do you see a pattern? Does it seem too complicated? Worry not: soon we will start designing our own BigBang abstraction, so as to recover the straighforward ways we had access to in C211.
