A standard 3-ring gimbal has a unique state (roll, pitch, and yaw) for each orientation in space except for two points where you get gimbal lock.
You seem to only need two of the coordinates (roll, pitch). Once the ball is on the spot, the rotation of the sphere about the vertical axis (yaw) does not matter. This rotation only affects the outer gimbal (#2 ...
This is still in rough draft phases, but this is my try:
I'm a dwarf of the world
But still in sight
