Raytracing - in Excel!

Off the back of my pseudo and "real" 3d excel models, I've made a raytracing model in excel which I hope demonstrates the basics of raytracing for any of you that are keen to learn!
As many of you will know, raytracing techniques are starting to be used more and more in game / graphics engines due to the increases in GPU power, and the concepts are also used in things like collision detection and game AI (e.g. "feeler" systems).
You can see the model in action here: https://youtu.be/m28jJ7CMp8A
And the model itself can be found here:  https://github.com/s0lly/Raytracer-In-Excel
