Nikola must be a very nice guy, as he is also providing the source code of the games as a download. The first game is "Shock", a variant of the Breakout game (see the image at the right). A second Silverlight application is a Chip-8 Computer Emulator with several 1970's games like Pong, Bomber, Alien, etc... Both are Silverlight 2 applications (currently working on beta 1 of Silverlight 2).
Lastly, he's also publishing links to interesting tutorials about Silverlight on his website.
Don't blame me if your work isn't finished in time. 😉
