Click and drag to rotate the cube. there are supposed to be green dots on the corners, but for some reason they are out of sync. It's harder converting JavaScript to scratch blocks than it sounds.
Thanks to Khan Academy for giving me the source code, and my dad for a bunch of debugging. Please stop hating on it, I'm tired. If you think you can do better, click See Inside to find the original JavaScript code and try for yourself.
