If you want to really amaze your PC friends, use the motion-sensing feature of your MacBook and the terrific (free) virtual desktop software VirtueDesktops to turn your laptop into a SmackBook.
Launch VirtueDesktops, then select it from the menu, and choose Preferences… from the drop-down list.
Select the Application menu item and place a check in the boxes Launch Virtue on Login and Enable motion sensor switching.
Select the Appearance menu item, place a check in the box labelled Animate transitions and then choose an animation type. I use (and amaze my friends with) the Cube.
Now select the Layout & Pagers menu item. Here you’ll need to specify the number of virtual desktops you want to use. I prefer having just 2, but that’s just me.
Finally, select the Triggers menu item. You’ll likely find that you don’t want to actually have motion-sensitive desktop changing enabled all the time (it can be annoying, esp. if you’re working with your laptop on your lap), so choose keyboard combinations (triggers) to change desktops. Apple-key + 1 and Apple-key + 2 works very well for me.
When you’re done, close the Preferences and start smacking! (not too hard, your Apple Care won’t cover damage done by over-aggressively smacking your MacBook/MB Pro) :)
