Credits: I learned how to make the 3D stairs illusion from "PIN KORO". The drawing of the illusion in the project though was by me. Here's the video if you want to check it out: https://www.youtube.com/watch?v=LcWLe_f-wQk All of the code was by me. All of the drawings and other stuff were by me. Notes: I also REALLY like the 3D stairs illusion too! I think it looks great! Enjoy!
