Snowflakes is a nontotalistic Lifelike cellular automaton by users BlinkerSpawn and danny that is omniperiodic. It is named by a very common 21 cell still life that has a 2 cell seed:

There are two very important small orthogonal spaceships:

The G is c/2, the R is 2c/4. There exist G guns for all possible periods, the lowest being 11. The same is true for the R gun, but no guns have ever been found of periods 9 and 10, the former being the lowest period possible.
Besides c/2 orthogonal, the only known spaceship speeds are 2c/6 orthogonal, 2c/19 orthogonal and 2c/12 diagonal, with the smallest examples being:

The latter two spaceships have since appeared naturally in C1 soups, and have a synthesis from G's. For all known speeds there are puffers, but only the orthogonal speeds have rakes.
A universal constructor is in the works by Goldtiger997 and several other users, which may lead to a very highperiod spaceship, much like Life's universal constructorbased spaceships.
