I'm always looking for people who use technology in ways unanticipated by the designer. Here is a great example. This guy took his Powerbook G3 and wired it into his car. Moreover, he did it the right way, fully integrating it into the car with steering wheel controls for controling the music, a touchscreen console LCD, usb port in the center console glovebox, and the powerbook in a docking station in the back where a CD changer would go. Add in his infrared adapter for added control, and you've got a heavily wired car with a powerbook that can still be pulled out for day-duty.

The best part is that with a platform like this, it's easy to add all kinds of new features likd GPS tracking, voice-activated email, or what have you, because now it's just coding instead of trying to integrate each new tool into a car not designed for it.
