Hi this is mine! I actually just came here to post this project but you beat me to it haha. Feel free to ask any questions about it
Hey James, I think you asked to see the code, here’s a link: https://github.com/haybur/Inf_Mirror_3.6_343_3D. It has some poorly named variables and functions so I hope it isn’t too confusing!

Thanks @Daniel_Haber !
@James_G I don’t know how close of a look you’re taking but any feedback or advice is always welcome
