What to watch
- It has a larger moving envelope than the LWSS.
- Its translated phase is easy to see at speed 4 to 8.
- It illustrates a family of related orthogonal spaceships.
Spaceships
Middleweight spaceship
MWSS
A wider c/2 spaceship with a larger body than the LWSS.
The MWSS keeps the same period and speed class as the LWSS while adding more cells and a wider envelope.

How to use it
Use it to introduce spaceship families and envelope size.
Open the pattern in the lab, reduce the speed, and use single-step mode when a phase change is hard to see. The green preview marks births in the next generation; red outlines mark live cells that will die.
