A modified example from the book "Smashing Node" using Socket.io instead of websocket.
For every visitor on the web page there appears a cursor mimicing the movement of the visitor's cursor.
You can check this example out at herokuapp but it looks smoother if you download it and run it locally on your computer. For it to run locally you must install node.js, then navigate to the folder via your terminal and execute the following:
npm install
node mouse-server.js
and you should have the example up and running on localhost:3700
