Yes, that's right, it's https://github.com/vnglst/stacked-game-of-life

The link was broken indeed. Should be fixed now. Glad you like it!

Could you make the number of history layers and their opacity configurable?

I asked Gemini 3.1 Pro Preview to generate the modern artworks as SVG for my Pelican Art Gallery. I particularly like the rendition of the Sunflowers: https://pelican.koenvangilst.nl/gallery/category/modern

Nice collection of visible bits that have no relation at all with art

bro why is called pelican art gallery if you have no pelican art in it.

Is this like 5d chess layers of irony or something im not getting through?

Nice gallery besides

Oh that's weird. Are you sure it was the basic link and not the one with count down mode?

The one I shared in the parent is for the New Year's countdown: https://tetris-time.koenvangilst.nl/?mode=countdown&to=2026-...

The basic link should show the current time, even at high speeds: https://tetris-time.koenvangilst.nl/?speed=10

Oh wait, I just tested it on a higher speed (20) and I see what you mean. It's drawing over the existing Tetrominoes! I'm going to max the speed at 10.

The year is coming to an end, and looking back I had a lot of fun building quirky, fun, and insightful visualizations. Agentic coding agents have been hugely empowering for me. In 2024 it was “just” autocomplete on steroids. Now it feels more like conducting, directing the agents to go where I please. Often they’re impressive; sometimes they fail at the simplest tasks.

What worked particularly well here was a test-driven (TDD) approach. I asked Claude Code to focus only on the algorithm for selecting the next Tetromino (the Tetris blocks), starting with tests. After that, things went smoothly, though it still took many follow-up prompts (around 100) to reach the final result.

Thanks I love the suggestions! Great ideas for the next iteration.

As I cannot change the title anymore I think that’s my best option now :-)

Wow this one is great!
