MAKE SURE TO USE TURBO MODE!! (Shift+Click the green flag) Change the rotation speed of the cube (or your model) using the sliders. You can press "See Inside" to access the code to copy your model into the Current Model (which is the one being rendered). To make your own model, add the point coordinates to your model list or default model following the format provided in the code comments.
I based the code off of a JavaScript project I created on Code.org (●'◡'●) You can view it here: https://studio.code.org/projects/gamelab/f6f1079e-1ded-498c-a5be-689388c1da8c/
