Spaceships
On February 17, 2013 Josh Ball discovered the first c/7 orthogonal spaceship, the loafer.
Using caterloopillar technology, Michael Simkin constructed a c/7 orthogonal ship on April 16, 2016.[1]
On February 4, 2017, Matthias Merzenich discovered 339P7H1V0, a large p7 width-19 bilaterally-symmetric c/7 orthogonal spaceship. These ships can be chained by nontrivial spark interactions to produce an infinite number of distinct c/7 orthogonal spaceships.[2]
Guns
Loafer can be synthesized from 8 gliders, allowing the construction of guns.[3]
gollark: I finished my codeguessing submission some time ago so I have time.
gollark: Sure.
gollark: Certainly. I assume it just needs TCP on some port?
gollark: I mean, me and heav would probably prefer to invoke JS-based dark gods.
gollark: This is also possible.
