+
+[The Raytracer Challenge][raytracer-challenge-github] is a project with the goal
+to write a raytracer from scratch in Rust, while showing each step of the way
+[as a weekly live coding session][raytracer-challenge-playlist]. Everything is
+documented, starting with implementing [Vectors][raytracer-challenge-vector] and
+[Matrices][raytracer-challenge-matrix] all the way to creating [Phong
+Lighting][raytracer-challenge-phong].
+
+November has been a busy month for the project with lots of visual changes in the
+raytraced results:
+
+- A [camera][raytracer-challenge-camera] was added to allow arbitrary views on
+  the [World][raytracer-challenge-world].
+
+- [Basic animation support][raytracer-challenge-animation] came along allowing
+  the easy creation of video sequences.
+
+- More realistic and life-like scenes due to [Shadow
+  Casting][raytracer-challenge-shadows].
+
+- As a new basic body type [Planes][raytracer-challenge-planes] came to life.
