I'm interested in deconstructing/reverse-engineering software of historical significance. I have a blog which examines the productivity software during the retro "golden age" of computing, from 1977-1995: https://stonetools.ghost.io
My for-fun development work tends to be in Pico-8, though I'm slowly moving to just plain ole' C with RayLib. A portable Zork built with Cosmopolitan LibC is on github. That single executable runs on every (?) 64-bit system you can throw it at. Check it out at: https://christopherdrum.github.io/posts/2025/04/porting-infocom-with-cosmo
A from-scratch rewrite of Mystery House (first graphic adventure game), PicoCalc (Visicalc clone), Eliza 8 (scriptable Eliza clone), and Status Line (z-machine interpreter, i.e. Zork, etc.) are all available for the Pico-8 at: https://christopherdrum.itch.io/
