 The second book in this series builds on the ray tracer you've developed here. This includes new
 features such as:
 
-  - Motion blur -- Realistially render moving objects.
+  - Motion blur -- Realistically render moving objects.
   - Bounding volume hierarchies -- speeding up the rendering of complex scenes.
   - Texture maps -- placing images on objects.
   - Perlin noise -- a random noise generator very useful for many techniques.
