First time ever I've learned C++ was actually on university and even thought I've never used it before I did manage to create two pretty cool applications that I really like (can't live without them):

Random desktop wallpaper picker: cpp_wall.zip. In short, you pick a folder (or folders - there is no limit) with tons of images and "WallChanger" will pick one at random. It comes as a Visual Studio 2003 project + EXE files. More info in the "readme.txt".

Windows Assistant "Wina": cpp_wina.zip. Cute little elf girl that will sit on currently selected window. Right click on her to see some settings for that window (for example: make it transparent or force it to always be on top). Only EXE file included + readme.txt.
