Mindflex, AR-Drone 2.0, Socket.io

Index_server_sockets.html is the client side of server_sockets.js.
Server_sockets.js takes input from 3 hacked mindflex headsets (you have
to specify the COM port in the code), uses the attention values from
each to control a different command to the AR Drone 2.0, and serves the
data to webpage using socket.io to keep things going in realtime. It's
my first shot at this kind of thing and if there's any obvious
improvements you can suggest, please let me know!
