## Anchor Directions and Anchor Arrows
For the ant on the sphere it is obvious which direction is UP; that
direction corresponds to the Z+ axis. The location of the X and Y
axes is less clear and in fact it may be arbitrary.
One way that is useful to show the position and orientation of an anchor point is by attaching
an anchor arrow to that anchor. As noted before, the small red flag
points in the direction of the anchor's Y+ axis when the spin is
zero.

In the second example, the child object points diagonally away

likely that this result will not be what you want. To get a different
result, use `position()` with `orient(anchor=)`, if needed.
