Turbo speed not required!
Please, see the newer version! http://beta.scratch.mit.edu/projects/10033647/ Don't get your hopes up too high (yet)! I have not made any built-in hidden surface removal/z-sorted rendering, meaning this method has limited possibilities. To make the surfaces show and hide at the right time, I made them only show between specific angles. Even with its limitations, I think this has the potential to be the dawn of a new era on Scratch.
