A small, cracker-themed block puzzle I cloned and polished for my four-year-old — built in plain vanilla JavaScript with synthesised audio, a Three.js bloom backdrop, and a deliberately forgiving combo system. Free to play, open source on GitHub.
What I wish someone had handed me on discharge day: the biochemistry of warfarin and vitamin K, the food atlas, the drug and herbal interactions, travel, and the daily operating procedure of life on warfarin with a mechanical mitral valve. Written engineer-to-engineer.
