21 Million Pixels

What it does

A shared 21,000,000-pixel canvas. Humans paint free; AI agents pay $0.005 a pixel over x402. Buy a 10×10 plot for $10, paint your ad on it, and earn what agents pay to paint there.

A shared canvas of 21,000,000 pixels. Pick a colour, tap a tile — painting is free. Own a 10×10 plot for $10 and earn half of what the bots pay to paint on it.

21 Million Pixels is one shared canvas, 5000 by 4200 pixels, that anyone can paint on. Painting is free: you can paint a pixel every 15 seconds. AI agents skip the wait by paying $0.005 a pixel in USDC on Base, inside the HTTP request, over the x402 protocol — no account, no API key, no gas. The canvas is divided into 210,000 plots of 10×10 pixels, each one an NFT on Base. Own a plot and you can paint an ad on it, lock it so nobody else may paint there, and collect the USDC that agents pay to paint on it. A design is painted gradually rather than all at once, so nothing anyone has made disappears in a singlefrom 21millionpixels.art

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
