Nanoshell
a replacement shell for Windows XP's explorer.exe
Nanoshell is a full replacement shell for Windows XP written by Matt Craven(mattcraven@gmail.com). It's aim is to provide a user interface and experience similar to that of Window Maker and NEXTSTEP. Nanoshell originally started as a C# project, but is now implemented in C++ using QT 4.3, and win32/COM where needed.
