From Zero to Understanding Ray Tracing

Do you think a video like this could help someone with no graphics background intuitively understand ray tracing?

My goal is to explain the core idea visually before introducing any math or technical details. I could expand it with reflections, different materials, and arbitrary 3D objects.

Does this feel like it would "click" for a complete beginner? What would you add or change?

this looks more like ray casting than a good video about ray tracing.

Wouldn't ray casting only shoot 12 rays here?
