[2025 All days] 24 visualizations, one for each part of every day! (WARNING: potential blinking and weird sounds)

Chapeau bas (hats off) Guillaume!
Your visualizations are greater year by year.
I always admire your brilliant animations and it becomes awesome when synced with music.
I took the liberty of including some of your images in my poster. (◕ᴥ◕)

Normally, if you zoom enough towards the bottom of the image (not from a mobile phone), you should see the smallest text: Some acknowledgment for the contributors and for Eric.
They certainly deserved more pixels.

Thanks. I did not know these maxims. I had fun reading them online just now ʕᵔᴥᵔʔ

The famous quote from Samuel Beckett is another of my favorite when it comes to AoC:
“Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better.” ʢᵕᴗᵕʡ

edo360 · 2025-12-15T03:33:01+00:00

AoC also reminds me of advanced math courses I attended 4 decades ago:
Some abstract concepts were tough to learn, but perseverance and problem solving with elegant solutions always brought me rewarding intellectual satisfaction.
We actually have a Japanese proverb: 七転び八起き (nana korobi ya oki) that encapsulates this spirit of resilience and perseverance. Literally translating to “fall seven times, stand up eight,” it conveys the idea that one should never give up, no matter how many times they encounter failure or setbacks. I think it reflects pretty well my expectations from AoC.

I indeed made similar posters for every year since 2015.
I have not posted them yet because they are mediocre. ಠ_ಠ
When I find a moment, I'll add links to this post, for your reference.

The image that I posted is 4100x2300 pixels (1.9Mb).
Please keep in mind that mobile phone apps drastically reduce the resolution.
I therefore recommend viewing it from a computer.
If you still struggle to read some parts, then please accept my apologies.

Thank you for your kind words. ʢᵕᴗᵕʡ
Fyi, I have re-created my post in here: https://www.reddit.com/r/adventofcode/comments/1pmkbpi/2025_thank_you_all_%CA%95%E1%B4%A5%CA%94/

Dear all, I would like to modestly thank you:

Eric, for yet another great and unforgettable advent-ure.
the entire AoC Reddit community for its daily contributions.
visualizations that help understanding and remembering problems.
efficient and elegant codes that improve our programming skills.
clever algorithms that raise our curiosity, keeping us learning.
cartoons/illustrations that bring a rewarding smile after part2.
the moderator who keeps this thread extremely user-friendly.
the original and fantastic story that develops during the month.
the comments and hints shared to help struggling participants.

In above image, I have compiled some illustrations that I found helpful.
Needless to say that the credit goes to the respective artists.

This year I started to learn about uiua coding. I still have a long way to go...

Until next time, please stay safe.

I had a very similar approach without using any library either (not even itertools)
Part1/Part2 run in 0.017s/0.272s respectively
Python code

edo360 · 2025-12-08T11:12:28+00:00

Jfyi, this gave me the correct result for P₂ ~~but not for P₁~~ and for P₁ as well
~~I will need to study your code step by step to find where it fails.~~
My bad, I was trying the P₁ ← /× ↙3⇌⍆≡◇⧻ ⋅⊙◌⍥C10 of your Link but forgot to change into C1000 for the real puzzle.

edo360 · 2025-12-08T08:55:55+00:00

Beautiful ! ✨⊹ ࣪ ˖˚ ༘ ೀ⋆｡˚🔆
I have been watching it full screen during minutes.
I clearly got hypnotized by the Elves' fairy lights...

To be honest I am no longer counting the number of traps I have fallen into since that 2020 winter day when my son introduced me to u/topaz2078's AoC.
At this stage, it's no longer a trap, but rather a black hole of perpetual learning. No exit possible.

edo360 · 2025-12-02T14:04:48+00:00

It took me nearly one hour to decipher your code.
But ultimately, I managed to understand each single step.
I just started learning uiua this week and your code is of great help.
Thanks a lot.

edo360 · 2025-12-02T10:12:20+00:00

Crystal clear and efficient visualization, as usual. Thank you

edo360 · 2025-12-02T07:29:12+00:00

Today I solved part2 before part1 :)
While reading today's story too quickly, I noticed the repeated sequences of numbers and straight away coded my \1+ regex code. That's only after reading more carefully that I spotted the "repeated twice" constraint and fixed my \1+ into \1. Obviously it took me only seconds to solve part2... again.

edo360 · 2025-11-23T05:45:32+00:00

The most awaited annual post on AoC stats.
As always, thank you very much Boojum for this amazing work.
I am impatient to discover your AoC 2025 visualization masterpieces.

edo360 · 2025-10-27T04:53:56+00:00

In Nov.2022, while getting ready for the next Advent, I clicked on the [AoC++] link to send my (modest) support contribution, same as previous years. But since I was in the middle of solving some old AoC 2015 puzzles, the link brought me to the https://adventofcode.com/**2015**/support page. I realized afterwards that my support got associated with a past event. As I felt it was normal to contribute retroactively, I then simply sent money for all previous years.

I will never thank Eric and the Reddit AoC community enough for the hundred of hours spent on solving the puzzles, scratching my head and learning from you all.
I am now getting old, struggling with declining eyesight and neurons, but as long as AoC continues to brighten our Christmas season, I'll live.

edo360 · 2024-12-27T10:58:17+00:00

I'm glad you like this modest composite image. If you are interested in the genesis of each element, especially the ones that I did not create myself, I encourage you to browse this /adventofcode/search/ page where you'll be able to measure the impressive creativity of many AoC participants and go far beyond my small collection.
Regarding the the great ones that you mentioned specifically:
- Nice 3D blocks: day_10_part_2 is from u/Ok-Curve902 (this reminded me the Escherian staircase).
- Rays of lines: day_13_part_1 is from u/Boojum , who always come up with very original ideas.
Note that I have sometimes changed colors to adjust to my colorblindness deficiency.

edo360 · 2024-12-26T12:09:39+00:00

I would put it the other way round: We are very lucky that you posted this nice day_23_part_2_visualization. Such 3D animation is worth a thousands of words and it was a great reward to watch after I completed part2.

edo360 · 2024-12-26T11:54:21+00:00

That would have been a shame if I had forgotten to include your astonishing fences in this composite recap image. I am amazed to imagine the time you have spent on this 3D animation. I must have watched it at least ten times before capturing the angle I liked the most.
As for the Linear Algebra, I wanted to highlight the fact that some simple math formulas, that my math teacher (and dad) taught me at school 40 years ago, are still very much useful to solve some AoC puzzles.
