- 1. Store a timer value (seconds elapsed) in the current script component (accessed through `self`).
- 2. A speed value. How many rotation steps to perform each second.
- 3. Increase timer value with the delta time elapsed since last `update()`.
- 4. Calculate which step to rotate to.
- 5. Calculate rotation angle (in radians) based on which step to rotate to.
- 6. Create a rotation quaternion with `angle` rotation around the Z axis.
- 7. Set the rotation on the current game object.
