Pixel Buy
1,000,000 pixels. $1 each. Take one.
What it does
1,000,000 pixels. $1 each. Paint one, or steal someone else's for the same $1. No accounts, no rules, no moderation beyond color. Draw first, pay after, like a real drawing tool, not a selection form. Import a logo to auto-fill a shape instead of painting by hand. Every purchase hits the live activity feed, and top landowners climb the Ladder. The canvas never sleeps. Always contested, always changing. Come stake your claim, just don't get attached.
A million pixel canvas. $1 per pixel. Paint your logo, attach your link, get the traffic. Anyone can steal it back for $1.
Pixel Buy is a public canvas of 1,000 x 1,000 pixels — exactly one million of them. Every pixel costs $1. Buy one, pick its colour, and it appears on the canvas within seconds. There are no accounts and no protected zones: any pixel, including yours, can be repainted by anyone else for the samefrom pixelbuy.lol

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
