Tetris Time
It's almost New Year's and here's an original way to show the countdown using Tetris. I'm sure something similar has been done before, but I had a lot of fun building this (TDD style) using Claude Code. After New Year's it can also function as a regular clock: https://tetris-time.koenvangilst.nl/ For the impatient, it's possible to increase the speed using url parameters: https://tetris-time.koenvangilst.nl/?to=2025-12-31T23:00:00....
In plain words
Tetris Time is a countdown clock that displays the time until a specified date using Tetris-style gameplay mechanics. After the target date passes, it functions as a regular clock. Users can adjust the countdown speed and target date through URL parameters. The tool was built using test-driven development and Claude Code.

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
