This is what I built in my home and this video is my own work. Both the computer and the software is self made. The interface is inspired by the LCARS interface from Star Trek.
Shown in this video are: - Agenda/Calendar - Shopping list (Groceries) - Rain radar - Train departure times (because the train station is nearby) - Library & Media player (connected to home cinema set) - Internet browser
Not shown, but also operational is bluetooth support (notice the Transfer button to send the shopping list to your telephone)
