Features

Basic Drawing

  • Users can set a display name and pick an avatar color
  • Users can create canvases and join/leave them
  • Basic drawing tools: freehand brush, eraser (visually removes strokes), color picker
  • Adjustable brush size
  • Clear canvas option (with confirmation)
  • Real-time sync - see other users' strokes appear as they draw
  • Strokes should remain visible during drawing (no flicker from polling)

Live Cursors

  • Show all collaborators' cursor positions in real-time
  • Each cursor displays the user's name and avatar color
  • Cursor icon reflects their current tool (brush, eraser, select, etc.)
  • Show a small preview of their selected color next to the cursor
  • Cursors smoothly animate and fade out when users go inactive
