The 2025 edition of the Logiker programming challenge has been announced via a YouTube video:
This year’s pattern is a snowflake, and I am very curious to see the approaches people come up with in BASIC to do this. I have some ideas, but none of them seem small.
This 19×19 image won’t fit on a CoCo’s 32×16 screen, but the challenge allows it to scroll off as long as it was printed to match. Using the 40/80 column screen on the CoCo 3 would work well.
Here is the info page for the challenge:

I somehow completely missed out on last year’s challenge, which was a present box, so maybe I’ll find some time to experiment with this one. I’ve never “entered” the challenge, but have blogged attempts here.
Are you in? Let’s get coding!
So annoying that they always use a pattern size that’s too large for the 6847. Effectively means that we can’t do succinct 6809 assembly on a Coco 1/2/Dragon
I was just thinking about this in asm, and how it could put it on the screen like a kaleidoscope if we could plot to all the character positions. Now any asm attempt has to just put a character out like BASIC would be, I guess?
