image: Circles on Sphere

This is an image generated by Illustrator script.

Basically, the method is simple. It is to draw an ellipse, then rotate it around the center of the large circle. This is not an accurate expression of 3D object. But I think it can not be a problem for the purpose of this case.

Light colored shapes mean that they are on the back side of the sphere.
At first, it seemed that they're sligntly unnatural in size, so I added perspective factor to the size of the ellipses.
