Toy Raytracer
I wanted to get some more experience working with Haskell, so I challenged myself to a Christmas hackathon and wrote a raytracer. A raytracer is a good project for working with a new language because it is complicated enough that you can fully explore a language's features without being too big of a commitment.
Right now the program is limited to Phong-shaded spheres with hard shadows, but if time permits, I will add reflective surfaces as well.
