When I evolved some patterns (literally) by hand in an uninteresting rule, I suddenly realised that pi-heptomino is a failed spaceship.

a spaceship, but actually any configuration of water cells is a spaceship, so it doesn't count.
I decided to turn it into a spaceship... and I did it. I called it
, because it's unique to me.
Then I realised that there are lots of rules that enable this spaceship. When I started rulegolfing these rules, I saw something moving away from the soup...
. It turned out to be very common in rule types that I call Class A and B.
This was a story about my two favourite spaceships.
