On Friday, OpenAI released GPT-5. The release triggered a wave of demonstration videos in which YouTubers showcase GPT-5’s programming skills in pair programming and vibe coding. Many of these examples revolve around creating simple, well-known games – things like flight simulators, Snake, or Angry Birds variants. Such projects exist in hundreds of versions online and are likely also in the AI’s training data. In these cases, 95–99% of the work is handled by existing libraries and frameworks.

I wanted to choose an example where it wasn’t about graphics or rendering, but about cleanly implementing logic with some complexity – something that doesn’t exist in identical form all over the internet. An obvious candidate was a small but clear-cut scenario: controlling a small above-ground pool with a pump.
