A modern, cloud-native tile server for Whole Slide Images. One command to start serving tiles directly from S3. # Installation (requires Rust, see alternatives below) cargo install wsi-streamer # On your local machine wsi-streamer s3://my-slides-bucket --s3-region eu-west-3 That's it. No configuration files, no local storage, no complex setup. Open http://localhost:3000/view/sample.svs in your browser to view a slide. Whole Slide Images are large (1-3GB+) and typically live in object storage. Traditional viewers require downloading entire files before serving a single tile. WSIStreamer takes a different approach: it understands slide formats natively, fetches only the bytes needed via HTTP…from github.com

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
