I have seen black macbooks get laser engraved (Kevin Rose's for example), but does anyone know how it would look on a white macbook? I have already found a local company to do it, just not sure how it would look on the white plastic....
The laser engraving on a white MacBook actually turns out black. The plastic used in the MacBook is specially engineered to change color when engraved. Here is the Epilog Laser page on the white MacBook.
