delete the 4 cache files found in var/mobile/Library/Caches/ (com.apple.SpringBoard.folderSwitcherLinen.0, 1, 2, and 3).

respring, this will update the multitaksing background for you

I have also included multiple changing wallpapers. To use these rename 
Wallpaper.htmlexample to wallpaper.html

I find its better to disable this by default as you may like to choose your own nARUTO pic (hd) as shown in example screenshots.


If you like the reflected doc simply remove SBDockMask@2x.png from Bundles\com.apple.springboard folder


Enjoy
