AstraPixels
A pixel-art solar system at its real current positions.
What it does
An animated pixel-art map of the solar system with every body at its real current position, computed from published orbital elements rather than copied from a list. Zoom from the Sun to the Kuiper belt, browse 171 catalogued objects with sourced facts, and see what the sky is doing for the next six months. Every rock is also for sale: claim an asteroid for $5, keep it forever, name it whatever you like. A name here is shown on AstraPixels only, and is not an IAU designation.
An animated pixel-art map of the solar system with every body at its real current position. Browse 171 catalogued objects, check tonight's sky events, and claim a body of your own.

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.
