This is a fun project I’ve been slowly improving over the past few years. It started as a fun technical experiment and has grown into a canvas where over 300 million pixels have been placed, one pixel at a time.It’s a single realtime canvas shared by everyone around the world. And when I say it’s global, I truly mean that. Communities have popped up everywhere from Germany to Japan to Azerbaijan. It even had quite the following in China before it got banned by the Chinese firewall.I call it an “infinite canvas”, but of course, infinite values don’t exist in computing. See if you can find the edge ;)

Happy to answer questions about this project!I've been using this project as a way to play with tech I don't typically use day-to-day in my paid work.It's gone through a bunch of iterations. It started almost entirely on AWS serverless services (Lambda, Dynamo, etc). That ended up being ridiculously expensive for this use case, so now it's a boring Go app on a cheap VPS talking to Postgres.The mobile app has also gone through some iterations, starting as a wrapper around a web app (CapacitorJS), and is now using React Native instead.

Hello Sean, long time listener, first time commenter. Huge fan of your work.
