My favorite was this project because it really shouldn’t be possible, it requires some unusual problem solving (kinda like code golf), but the best part is seeing people’s horrified expression when they realize

1. The monstrosity works
2. There’s no real alternative

(I’m working on a video that explains it, but until then the readme and stack overflow post will have to do.)

A decade ago I reverse engineered the Macventure game engine, allowing you to play Shadowgate and Deja Vu etc on modern oses. The current copyright holder then paid me to iron out the rough edges and create the official ports currently on steam.

I made an app for track my paints for mini painting. Making the ui was really fun.
