A drawing board several people share at once, over a real WebSocket to the arcade's own server. Your strokes appear the instant you draw them and are sent afterwards, while everyone else's cursors are eased between the positions that actually arrive rather than teleporting. Open it in a second tab to draw with yourself, and switch the smoothing off to see what the network really delivers.
Controls
Mouse: Click and drag to draw. Open the page in a second tab to draw together. Type a room code and press Join Room to move to another board. Buttons mark you ready, clear only your own strokes, and toggle cursor smoothing.
