Description
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....

Concerns raised: High speed rendering causes Tetrominoes to draw over each other and erase progress, Algorithm produces gibberish output at certain speeds, Blocks fall without proper collision detection at high speeds
Feature requests: Speed limit optimization to prevent visual glitches, Improved collision detection algorithm
