Use TURBO mode to see it. (Press the <Shift> key and click the Green Flag for TURBO mode). Yeah so I spent two afternoons making a raytracer in scratch. That is only on line long. Yeah... Uh... Look inside if you want to see for yourself! And yes, this is a real raytracer. No fakery to save on blocks or performance. Ray sphere intersections and ray plane intersections is carrying this project hard The shadow system was a bit broken as you might be able to see, but with so many blocks in one line, it was practically impossible to debug, so I tried to tune the angle to be as good as it could be. If you think I should just remove the shadow let me know!
Thanks to @Scratch-Minion for this genius 9 year old challenge that I am only now participating in, it's a great idea!
