Simple Curves

I'm learning a completely new language. It's called processing and I feel for the most part that it's over my head. I'm learning the bare bones and even that puzzles me but hopefully with some time and practice ill be fluent in the more complex parts. A class assignment is to create a stationary sketch using the simplest elements. Here is what I have so far in both code and physical form; it's not too hard to figure it out because this sketch is SO simple so see if you can. I'll share the final sketch when I finish. Eek!
