After seeing the Photoshop 1.0 source code posted here yesterday, I became curious to see how an LLM would deal with porting it to the web from the original Pascal source. I used Codex CLI with GPT-5.2-Codex-Max.

The result is here: https://photoslop-1.com

I wrote an account of the process here: https://photoslop-1.com/port

And have a transcript of the session here: https://photoslop-1.com/transcript

Well, the domain name for the project is definitely great! :)
