Here is another Code contest for students on Open Source from Google.
The Open Source Geospatial Foundation would like to extend a welcome to all SoC students. On this page you will find links to a host of ideas organized by project. You will find ideas ranging from the depths of computer science graph theory to the heights of visualization. One thing all these ideas have in common is lots and lots of spatial data.
These ideas are *only* to motivate you, and serve as example of the kind of hills we want to charge up. Your own ideas are more than welcomed – they are encouraged. We view you as the next wave of open source leaders; show us what you’ve got.

This is not only helpful for students and even for GIS community to know latest development trends in Open Source GIS, ideas, prespectives, future arena etc. If you are G-enthu (GIS Enthusiast) go through your favourite open source project.
