Show HN: An infinite shared pixel art canvas

[seangransee]

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.

I work for a company that solves this problem. If you're interested check out my profile or hit me up! We may be even cheaper than your VPS (and certainly more reliable).
