A unique entry in the MAKE blog shows off a Powebook etched with a 19th-century engraving of a tarsier, a nocturnal mammal related to the lemur (also the vi book cover image from O'Reilly). This is not something you can do at home, unless you have a $20,000 laser cutter laying around in the garage :) The entry page contains a few photos and since the entire process was recorded a video has been announced as well. I wonder how many people would use such a service on their Powerbooks if Apple made it available. They aready engrave iPods for free anyway.
