Setup your apple so that smacking the side of the screen changes the virtual desktop. The link is a video showing how it works. WOW. When used with the Cube... I'm gonna get this working. I just got this working. It is badass.

Here is how to do it:

after playing with smacking my laptop around i thought it was honestly easier to use the shortcut keys that virtuedesktop has and looks just as cool.

my version for intel owners: easy and painless

download and install VirtueDesktop (which is a pretty cool app in itself)
http://virtuedesktops.info/

Start the app after adding it to your Applications folder

download AMSTracker:

download smackbook:

extract smackbook to a folder, place it wherever you want on your HD (I chose applications). then extract AMSTracker, and put AMSTracker in the smackbook directory. From Terminal, navigate to the smackbook directory and run 'perl smackbook.pl &' without the quotes and command-H to hide terminal if you want. voila, you're done. smack away.
