Noah's ark
Noah's ark is a diagonal puffer that was found by Charles Corderman in 1971. It consists of two mutually stabilizing switch engines and is thus an ark. Its name comes from the variety of objects it leaves behind - in particular, every 1344 generations it produces 42 blocks, 40 blinkers, 22 beehives, eight loaves, four gliders, two boats, two block on tables, two long boats, two ships, and one beacon.

A 3-glider synthesis of a switch engine discovered by Luka Okanishi in March 2017 allowed for a 6-glider synthesis of Noah's ark.

gollark: Same issue and now they cost more.
gollark: Bigger batteries → more motor power → you need more batteries again → æææææææææææa.
gollark: You're subject to rocket-equation-type issues.
gollark: Solar panels are unfortunately not good enough to keep drones airborne.
gollark: Anyway, I think the main issue with droneswarms is that they would run out of battery quite fast.
