For @MiniMacro Basically, it's just drawing a skinnier and skinnier oval every time, then drawing a wider and wider oval, then it repeats, making it merely look like it's 3D. It's not actual 3D, it's just an illusion. To make it get thin and then wide, use the properties of sine. Sine gets larger and larger until it reaches 1, then gets smaller and smaller until it reaches -1. Just multiply the sine by whatever your radius is, and you have 3D. I hope this isn't too confusing. :)
