Mini game 'I am speaking' to showcase credibility of competencies

I just finished a quick 3D mini-game as preparation for the folks attending my workshop 'Let's talk about competent people' at Online Educa Berlin 2010. It is alpha version, so it is a start. But is is fully functional. The game was made with Thinking Worlds and runs on Windows.

You can download it here:

In the game, you have a limited number of hours to build credibility on the competence of public speaking. You need to trade off time, money and credibility in Learn, Do or Share activities. The credibility points you score are based on the survey I've conducted as part of the book.
