I dug out my Pascal code for an image editor I wrote roughly around 1997-1998 time, used LLMs to translate it to python and then used pygbag to make it run in browser using web assembly. End result here, enjoy:

Hah, was just going through some old files and I found my graphics editor I wrote in Turbo Pascal in 1997 as a teen. And thanks to the miracle of DosBox it works! On my M2 Mac! It had that cool pixel mixing effect, I've never seen elsewhere implemented.
