Edge-repair spaceship 2
Edge-repair spaceship 2 is a c/4 orthogonal edge-repair spaceship that was found by Stephen Silver in November 2000. Leading up to its construction, its T-tetromino component was found to be self-repairing by David Bell in October 2000. Soon after, Silver observed that it could be used to delete beehives, and thus created this spaceship.

This is the smallest known spaceship that uses this particular edge-repair reaction, and it contains two copies of it.

gollark: Also, screenshots.
gollark: But it's kind of bad.
gollark: I mean, if you want the code *now* for some reason, I'll give you it?
gollark: Yes, Lua exists and I could embed it somehow, but there are !!FUN!! challenges with that:- the API is kind of unsafe so the Rust wrappers are not great- I would also have to write a bunch of glue code to allow interacting with pages and whatever, which is especially hard as my code is asynchronous- I'd *also* have to work out a nice way to integrate scripting into the interfæce still.
gollark: No, I would build some highly accursed migration tool.
