In Japan, many people spend way too much time customizing their laptop computers (warning: long load time!), especially Apple PowerBooks and iBooks. If you own or plan to buy a new iBook, the fine Vermont company Small Dog Electronics will do something like that: they'll convert the translucent white casing into a completely transparent one.
The operation is costly ($375 US), since it means removing the iBook's case, soaking it for about 18 hours, scrubbing the paint off the inside for about four hours, and then drying, cleaning, and reassembling everything. But when you're done you can see the innards of the machine while you use it.
Or wait a week or two and read the instructions online. (They're not posted yet, but will be shortly.) Risk your own machine to this cool but warranty-voiding procedure!
