Not too long ago, weabout modder Eddie Zarick, who turned his MacBook logo into a psychedelic LCD display.
You'll need to be quite a handy person to complete the tutorial, knowing soldering and being able to dismantle a computer and a LCD. Also, you will lose one USB port in addition to losing the warranty.
If the tutorial is too tricky for you, you can still bid for Eddie's modified MacBook on eBay. The highest bidder in the last auction didn't follow through on payment, according to Zarick's page.
