1D-Pong Game at 39C3
Building a 1D-Pong game is a bit of a rite of passage at the Chaos Communication Congress. I was inspired by a version I saw at 38C3 and built my own interpretation for 39C3. Lots of people enjoyed playing it and even Elliot Williams featured it in his 39C3 Hackaday Podcast. And I can attest: it's truly fun because it's sooo simple at first sight - but wait until the speed increases... Not a bad work to fun created ratio for such a little project. I used the opportunity to play around with Claude Code on my preexisting codebase to publish a nice-ish repo on GitHub. It worked great without…
In plain words
This is a 1D-Pong game built for the Chaos Communication Congress, inspired by similar projects at previous events. Players control a paddle on a single dimension to hit a ball back and forth, with difficulty increasing as speed rises. The game is designed as a simple but engaging interactive experience, created with Claude Code assistance and published on GitHub for developers interested in building their own versions or variations.

I used the opportunity to play around with Claude Code on my preexisting codebase to publish a nice-ish repo on GitHub. It worked great without any hitch or compile errors - impressive. What a nice way to test some capabilities. Have fun with it an build your own version. And there are soooo many ideas that could be implemented. I am waiting for your feedback! Will we end up with a league of networked 1D-Pong games? ;-)

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
