The Nintendo Game Seminar is an annual event that lasts around 10 months, allowing students to understand the professional process of game development. Last year, those student teams have produced 4 different titles which can now be downloaded from DS Stations over the next few months.

There are no plans of producing these titles commercially but check out the official Nintendo site for some screenshots.
