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: That is true, but I did have a small further idea regarding that.
gollark: A CLI thing at the top where you can input an item, then a set of icons below which you can click on to autocomplete the command.
gollark: I still think a hybrid approach would be better.
