A spaceship repeats after moving
A Life spaceship is not just an object that looks mobile. It returns to the same phase after a fixed number of generations, but translated to a new position.
The glider is the smallest and most famous case. It moves diagonally at c/4. The lightweight spaceship moves orthogonally at c/2, making it the cleanest comparison after the glider.
Speed notation answers a real question
Speed notation answers a practical question: how fast can information move across the board?
Loafer is useful here because it gives a modern, compact, non-standard example: a slow orthogonal spaceship with c/7 speed. That makes it a good bridge from classic textbook patterns to community discoveries.
Signals make larger machines possible
Once a moving object can be produced, reflected, delayed, or absorbed, it becomes a signal. Glider guns, eaters, reflectors, and conduits all build on this idea.
That is why spaceship pages should link forward to guns and Life engineering pages rather than ending at motion alone.
Working takeaway
Use the glider for the first moving pattern, LWSS for orthogonal motion, and Loafer for readers ready to go beyond the classic spaceship family.
