Use the sliders to move the cube around, or use WASD to move the cube around too as if you are a person walking towards the giant cube.
Thanks to @Mathmathmath for creating the first part of the tutorial on how to create wireframe cubes! *since i completed this to demonstrate the steps mentioned in the first tutorial, it is unintentionally a Glitchy Wireframe Cube. Oofers. Ah well, at least its a cube. Thank you so much for allowing me along with everybody on scratch *that wants to learn about wireframe* to learn the basics of 3D graphics using the wireframe method!!!!!!!!!!!!!!!!!! I have always wanted to learn how to create 3D games and simulators so completing this scratch project earlier today was a dream come true! Thank you so much @Mathmathmath
