Ray Tracer Checkpoint #3

After refactoring a majority of my source code and working extra hard I now have a ray tracer which does proper Phong shading, runs in parallel, use procedural textures and can do reflections. For the purpose of this entry I'm simply focusing on the Phong shading. Below is an updated screenshot of my renderer with Phong shading enabled. The image may look different from the previous entry because I tweaked the image size and the locations of the spheres a bit.
