I just thought I would let everyone know that Windows 7 allows you to have a changing and dynamic desktop background of all the frames your computer has rendered for Electric Sheep. It can acomplish this out of the box with no additional software.
1) Go to your "Libraries" and create a new one called "Electric Sheep JPEG" or similar.
2) Add C:/ProgramData/ElectricSheep/content/jpeg to the library. You can navigate to this hidden folder by clicking once in the open area in the address bar and typing out the folder path.
3) Right click on the desktop, choose personalize, and select the desktop background option. For "Picture Location" choose browse and navigate to your newly created library! Windows should automatically slecect all the pictures in the folder and then you can manually set how long of a duration between backgrounds you want.
that's cool
And you can also replace the desktop background with the running ES screensaver using Vital desktop 1.4.2
