If you love cars - in particular the Toyota iQ (which I don't believe is available over here) - and own a Macbook, this is the perfect screensaver for you. After installing, you can enable the screensaver by holding the Menu button on your Apple remote for two seconds, and the car will appear on screen as it enables the alarm. Then, if anyone tries to pick up your Macbook, or touch the keyboard, the alarm will go off.
Of course, considering how pretty much every Apple remote automatically controls every Apple computer, it wouldn't be too hard to work around this, as a security feature. But it's still a pretty cool form of marketing from Toyota...
Hit the link to download the screensaver for yourself.
[Toyota - Thanks Tom!]
