This is the result of a Saturday spent working through the PragProg book on CoffeeScript, which is currently in beta.
Inside you will find a Scrabblish realtime multiplayer word game
You'll need CoffeeScript, Connect, and Socket.io
$ npm install coffee-script connect socket.io -g
Start up the server and invite a friend
$ coffee server.coffee
=> Browse to http://localhost:3000 to play
