Do you know students who are interested in doing some game programming developement? The Visual Studio Express group just opened a new web site with game programming code and resources and a contest that students may want to enter. The site is called Upgrade Your Game. There is probably enough there to keep some students busy writing code and having fun with it all summer long. Plus they can win a some really fun prizes in the related contest.
At the site students will find the code for four complete and simple games in their choice of Visual Basic .NET or C#. There are also webcasts, some more complex games and links to other resources for people who want to learn about programming games.
Who knows but you may find some things you can use for projects next school year. Or at least some things to keep people busy as this semester runs to a close and students look for semester projects.
