Your Best OCA Discoveries
Posted: August 21st, 2025, 11:03 pm
This is a thread for collecting the best of the best of patterns from the OCA forums.
Rules:
-You can only post one pattern per person (or headmate, if there are multiple who do CA).
-The pattern can be of any size, but must be in one rule. The pattern should ideally showcase just one thing, but I guess rule pattern collections are fine.
-You can add text to posts to explain it and give attributions or related links. Try to keep the text in the main body to a paragraph or so, but you can put more inside a code tag (which has a limit to the amount of space it takes up, so that solves the text wall problem, so there shouldn’t be any issue with text length when using it)
-You must have contributed in large part to any pattern you post; you can't post a pattern showcasing your random INT rule but made up almost entirely of other people's finds in it, or a pattern showing a macroship someone else made that uses a reaction you found. Use common sense.
-No using hybrid rules to get around the one rule restriction. Ruletables not intended to be hybrid are fine.
-You can change your entry in the thread at any time. Please edit your post to do so, don't post another message.
-Please avoid discussing things posted in the thread in this thread. It's intended to be a gallery. If you want to post a comment of some sort on something someone has posted here, do it in a dm or by a cross-thread reply.
Here is my nomination: A blinker-based Fibonacci counter found while manually rulegolfing.
Happy posting!
