Use the left and right arrows to rotate the figure. If you think about it coming outwards, it will look like it is coming outwards, and it will look more like a cone. If you think about it going inwards, it will look like it is going inwards and it will look more like a pipe. If you can't see it: follow the smallest circle with your eyes to make it come outward. keep your eyes toward the middle to make it go inward.
