Simple ping-pong browser game (using canvas and socket.io on the client side). Node.js used as a back-end server. To start the game you should install nodejs first (http://nodejs.org/#download) Then start the server: $ sudo node server.js Finally open two browser windows and point both to http://localhost:8081 Use 'Up' or 'Down' arrows to move your racket. Press Spacebar to start the round (only if two players are connected to the room) Demo version: http://germaninthetown.com/pong NB: since the site with demo is hosted in the US user could experience a little lag while playing if one or both players are from Europe or Asia Tested and works in Google Chrome 8-9 and Firefox 4
