14NYC has a bunch of traffic cameras and makes them available through static images [like this one](https://webcams.nyctmc.org/api/cameras/858ef4e8-5058-4db2-96e2-70f71b65aa24/image). If you refresh the page you'll see the image update every 2 seconds or so. I thought it might be fun to make these cameras viewable as an ASCII art video feed. I made a [small library](https://www.val.town/v/maxm/imageToAscii) that takes most of its logic from [this repo](https://github.com/victorqribeiro/imgToAscii). You can see a basic example of how to convert [any image to ASCII here](https://www.val.town/v/maxm/asciiImageExample).

16I pull in [NYC GeoJSON from here](https://observablehq.com/@miaozhang/maps) and then hook up a Server-Sent Events endpoint to stream the ASCII updates to the browser. (Polling would work just as well, I've just been on a bit of a SSE kick lately.)
