AndLinux

[Steven Picard]

This sounds pretty cool.  Someone at my work pointed this out to me so I'm going to give it a try when I get a chance. 

AndLinux enables you to run Debian based Linux apps seamlessly as part of Windows.

And along the same lines: Wubi

Wubi is an unofficial Ubuntu installer for Windows users that will bring you into the Linux world with a few clicks. Wubi allows you to install and uninstall Ubuntu as any other application. If you heard about Linux and Ubuntu, if you wanted to try them but you were afraid, this is for you.
