Only 33b for a complex snowflake? Dr. Beep made the unthinkable possible within the #VCCC2025 (Christmas Challenge 2025). Check: https://demozoo.org/productions/383789/ #sizecoding #vintage #retro #vccc2025 #BASIC #assembler #6502 #z80 #advent #apl #MerryChristmas

#vccc2025 results are in, so I made my entry public: https://mmphosis.pythonanywhere.com/vccc2025/

I was in the #Applesoft #BASIC #AppleII category, with my 171 bytes #applesoftbasic entry.

#vccc2025 results are in, so I made my entry's repository public: https://github.com/colinleroy/vccc2025

@a2_4am did not participate so I got first place in the #AppleII category, with my 72 bytes entry 😊

It's more than twice bigger than the smallest entry, a ZX Spectrum version that fits in... 33 bytes! 😮

It's okay, they kindly extended the deadline by a few hours, and I was able to submit my entry. #vccc2025

@colin_mcmillen Thanks for the heads up about #vccc2025! I've been poking at it on and off since you posted, and I think I'm at the point where every attempt to make it just a bit smaller ends up making it larger so I must be done. Submitted!

I updated my #vccc2025 entry so that the binary is the bootsector, no need for ProDOS. This loads much faster ! (And also provides you reader a spoiler, you can now guess that my code is less than 512 bytes - which is a very low bar, given that the pattern to reproduce is 18x18=324 bytes)
