An ellipse is nothing more than a circle projected in 3d? ;^)
An ellipse, take a parametric circle and use different x and y radii. However, Think of rotating a circle in a 3d projection. It visually looks like an ellipse. So, I always found that interesting. If I take an ellipse in 2d, it has a rotated circle "counterpart" in 3d? Fair enough, kind of? ;^)

Circles galore? ;^)
