Move your camera around using the sliders, move the light around using the sliders, and see how realistic a ray tracer can be. It can still improve, but even without reflections or ambient lighting, it is still very realistic for such a simple engine. Mobile friendly, I guess.
Use Turbowarp so it is actually realtime: https://turbowarp.org/837112521?fps=240&hqpen&turbo thanks to ArunRocks for his amazing tutorial on how to practically make a ray tracer in python, not just theoretically, like most tutorials I found.
