Just a quick update on the Tuxdroid / Java story. I followed the wiki page describing the installation for the 2.0 beta software and launched the new control center (which is entirely written in java).
The screenshot above shows this UI and it looks and works awesome. It has a lot more possibilities then the Python based 1.x UI and the attitunes stuff now really works. Attitunes are some kind of scenario's you can _play_, instructing the droid to do and say stuff. If you take a closer look to the screenshot, you can see the "Computer Alert 1 Nl" attitune highlighted. Pressing the play button executes the attitune and makes the droid speak and move.
Using the UI you can also download, install and execute attitunes contributed by other people from the Tux Is Alive website.
Anyway, I've checked out the code and I'm going to take a closer look at it.
