Projects & blog
I build free web tools, produce knowledge, and draw pixel art.
Free, private browser apps that keep your data on your device. A blog that goes wider: about whatever I'm learning, thinking, or building. And pixel art, made pixel-by-pixel.

About
I'm Martin Black. I'm a learner more than anything else - mathematics, computer science, physics, and sciences broadly. I learn a lot, and I keep a personal zettelkasten (600+ notes) as the place to manage my knowledge.
I build the projects here with AI assistance - vibe coding. The ideas, the testing, and the calls about what stays and what goes are mine. If that means these aren't "my code" in the traditional sense, I'm okay with that. They're my projects.
I draw pixel art by hand - no AI. It is drawn pixel by pixel - slow work, and entirely mine.
