I started Twitter integration today.

The Idea is to have  a webinterface on the Raspberry Pi.
The Pi is connected over wifi to your  smartphone and has internetaccess trough Thetering.

Now users can send tweets to @blinkenschild and those are displayed in realtime on the webapp / Smartphone.
If the carrierof the Blinkenschilds want to show the tweet, it just needs to be selected from the list and is given to a service on the Raspberry that displays it in scrolling text as shown above.

The webinterface is not even started yet, but we do have the command line tool ready to display the actual tweet.
