<p>Welp, I'm pretty happy with my effort on this project. First, I completed the entire Ray Tracer project in two days (as advertised). I wrote what I consider to be non-clever Rust and didn't think at all about optimization or anything too sneaky. I also I didn't type `.clone()` once and used Rust idioms such as `Option<T>` when it made sense. The final project ran about 4-5% faster than the original C++ code when I measured it at the end.
