It’s a game! I am happy to have it finally accepted in the market place! This app has been really fun to develop and to create, since it’s a game and it’s my first game. Here’s the link:

While devleopping it, I really could get a deep understanding of Blend, storyboards, doubleanimations, rendertransforms and all these sweet little friends that you get to know in the wpf worls. I guess such an app is never really finished and can always be polished, but after 6 weeks work developing it (and I have a full time job, a wife and a kid), I feel quite exhausted and am just happy to relax a little.
So here it is! I hope you won’t find it too badly designed, feel free to express your remarks and please don’t be too harsh…
