Looking at the student projects for Google Summer of Code on the Mono platform brings me nice memories from my own days in college when I worked on EtherYatri.NET. It is good to see that many participants have setup blogs where they update about their progress as they go along implementing.
For instance, check out Jey Kottalam's blog on his project GCC-CIL which aims to write a backend to GCC4 that generates CIL byte codes, to allow programmers to easily port existing code written in C, C++, Pascal, etc. to run on an ECMA CLI platform like Mono or Microsoft .NET. Or, check out Michael Dominic's blog on his project Diva - a video editing GUI tool using Mono, Gtk# and GStreamer.
