-series [Raytracing in One Weekend][weekend].
+A raytracer written in OCaml. It supports diffuse("matte") and
+reflective("metallic") surfaces.
+
+The design of the software roughly follows Peter Shirley's mini-book
+series [Raytracing in One Weekend][weekend] which presents a raytracer
+in C++. I've adopted the programming style to suit the OCaml's
+functional style.
