Make your own Wi-Fi teleprinter / Play teletype demo online (teletype.online)

I take some time to understand and to explain myself but maybe this will explain to you better http://www.austinchronicle.com/binary/cc5c/front.jpg but online and packed with a fancy pretty box. The demo in where you need to login with facebook are pretty too in design, according the website and box itself and you can send messages like you'll se in your teletype to other users (and that's it, i think..).
