I made a live Etch A Sketch that everyone draws on together. It's one shared 4000×4000 canvas, and you see other people's pens moving in real time. Like the real toy, you only get one continuous line and can only draw or erase.
If you want to draw something more intricate, there's a free API you can post your stroke coordinates strokes to: https://graciegould.com/api/etch/stroke (example under the API button on the page).
I'd love feedback on how the drawing feels and on the API. No profanity please.
