What you need for this:
-ADW Launcher EX
-Kindle Fire Setup files (Click)
ADW Launcher EX:
Gridsize 5x7, hide icon text, transition "slide", dock disabled, 3 Homescreens, infiniti scroll.
3 Custom Screens, set backgrounds from the Kindle Fire Setup files (they're numbered), transition "none".
Set the Phone, SMS, Email, Gamesfolder, Launcher icons on the menubar and make them transparent by using the "transparent.png" from the Kindle Fire Setup files.
Place some Desktopvisualizer widgets over the big icons in the center and make them transparent, too.
Now put some of your favorites Apps on the bottom two lines (Maybe with an icon theme, I'm using "Suave HD" icons)
Do this for the next 2 Screens and you're done!
