This is a completely pointless layout which acts like Microsoft's Flip 3D

You can use this module with the following in your ~/.xmonad/xmonad.hs:

 import XMonad.Layout.Roledex

Then edit your layoutHook by adding the Roledex layout:

 myLayout =  Roledex ||| etc..
 main = xmonad defaultConfig { layoutHook = myLayout }

For more detailed instructions on editing the layoutHook see:
