A gravity hill is a place where a slight downhill slope appears to be an uphill slope due to the layout of the surrounding land, creating the optical illusion that water flows uphill or that a car left out of gear will roll uphill. Many of these sites have no specific name and are often called just "Gravity Hill", "Magnetic Hill", "Magic Road ...
Distances between points are the same as between image points of an elliptic motion. In the case that u and v are quaternion conjugates of one another, the motion is a spatial rotation, and their vector part is the axis of rotation. In the case u = 1 the elliptic motion is called a right Clifford translation, or a parataxy.

Elliptical domes have many applications in architecture; and are useful in covering rectangular spaces.The oblate, or horizontal elliptical dome is useful when there is a need to limit height of the space that would result from a spherical dome.
An ellipse (red) obtained as the intersection of a cone with an inclined plane. Ellipse: notations Ellipses: examples with increasing eccentricity. In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant.
