A while ago I created a simple Android wallpaper, which can be found on Deviant Art here. The Wallpaper has a Creative Common license, its really nice to see someone making use of something I created, which I had almost forgotten about. Below is some text about the Guardian Project.

The Guardian Project aims to create easy to use apps, open-source firmware MODs, and customized, commercial mobile phones that can be used and deployed around the world, by any person looking to protect their communications from unjust intrusion.
The Android operating system created by Google provides an open-source, Linux-based foundation on which this project is building. From sleek, stylish smartphones to large format e-book readers, Android provides the most creative, functional and open platform on which to base this type of work.
The combination of Android and Guardian will create the most secure, trustworthy, mass market consumer smartphone solution for improving the privacy of our daily lives. Whether your are an average citizen looking to affirm your rights or an activist, journalist or humanitarian organization looking to safeguard your work in this age of global communication, Guardian is the solution for your mobile security needs
