Here are some "counterfeit gliders", looking like a glider in some phase, but having period 1 and moving at either 1c/1, 2c/1 or 3c/1. Since it would be annoying for readers (including myself) to have to scroll through a lot of similar short snippets, I grouped similar examples to save vertical space.
In all examples, the cellular automaton is two-state, isotropic, defined using a fully-symmetric weighted neighbourhood with range at most 3. I did not find any p1 orthogonal 3c/1 beta-gliders (o$b2o$2o!) within those restrictions (otherwise there would be one more snippet at the end).

Code: Select all

# p1 orthogonal c/1 alpha-glider

Here is a 'counterfeit glider' I found in a rule containing many large 'snowflakes':

Code: Select all

x = 3, y = 3, rule = B2-ae3acjr4ew5ejqy6ak8/S02-ci3ainy4-anqrt5cn6ci7e
b2o$2o$2bo!

The 'snowflake':

Code: Select all

#C The final population is 52.
x = 3, y = 1, rule = B2-ae3acjr4ew5ejqy6ak8/S02-ci3ainy4-anqrt5cn6ci7e
obo!

Random pattern:

Code: Select all

#R B2-ae3acjr4ew5ejqy6ak8/S02-ci3ainy4-anqrt5cn6ci7e
!
# [[ RANDOMIZE ]]

EDIT: By randomizing S3q on every generation, it is possible to turn the 'glider' into a wandering spaceship.

It's most of the rules are either very explosive or die almost instantly.

EnumPattEvo, which stands for Enumerate Pattern Evolution, is a program for finding rules that support certain patterns.
