My pipes game just got two new grids =)
I like the mix of hexagons, triangles and squares - hexapipes.vercel.app/rhombitrihex...
And the triangular grid is just pure minimalism - three distinct tiles and that's it hexapipes.vercel.app/triangular/5

A playlist of all the animations I made for #AdventOfCode 2024:

Managed to do a total of 14 days with #py5. Curiously the number is exactly the same as in '23 when I used #pygame. Each video has a link to the animation source code if you wanna see the messy plumbing)

All done with #AdventOfCode 2024. Fun ride as always!
Most memorable days for me:
- Day 14 (find the tree)
- Day 21 (robots inception)
- Day 24 (so that's how binary addition works!)
#py5 was very nice for making animations and I learned to use a statemachine to manage vis data

Thanks, #AdventOfCode, now I know how to construct a binary addition apparatus from logic gates 🤯
I submitted a handcrafted part2 answer earlier but I've now written some code that finds the swaps. Who knows if it works on other inputs =)

I've completed "Linen Layout" - Day 19 - Advent of Code 2024
adventofcode.com/2024/day/19
First I threw together some memoized recursion - worked fine but took 1.7s to complete both parts. That was kinda slow so I looked for ways to speed things up and managed to make it 20x faster!

I did a binary search in part 2 in my actual solution but watching how the path rebuilds after every new obstacle is pretty fun too.

Inspired by @gereleth.bsky.social and her very nice visualisations of solutions to #AdventOfCode challenges, I've tried to build my own.
This took a while, but here is a first attempt for day 12. I used #pygame to draw the frames and #ffmpeg to build the video.

I don't have a good day 12 animation yet because damn, getting a sane ordered contour was much harder than just counting sides.
But something finally works even for the crazier shapes like this one.
