Hey - bigdraw is a little project I've been working on which lets strangers to draw together on a shared canvas. No signups required - just click on a tile to claim and draw on it. It's inspired by r/place, One Million Checkboxes, and JSPaint.The backend's a Go+SQLite server that handles submissions and generates map tiles (think OpenStreetMap). This lets you zoom out to see tens of thousands of drawings on one screen. In theory... there are only a hundred or so drawings so far.On the frontend, 2D canvas is used for rendering the "map" tiles and the grid. The fog is rendered with WebGL.
