Requires socket.io.

Put socket.io client in socket.io/ directory.

On server install socket.io with npm install socket.io and run the server with node server.js.

Run your favourite web server in the directory, then point your desktop browser (best view on Safari, sorry) to desktop.html and your mobile device (iphone, android or ipad) to mobile.html and watch the magic.
