Not all hacks have to be about good looks, really. Such is the case with the hack that Dave Derwin recently undertook in gutting an old Walkman-style portable AM/FM radio / casette player and turning it into a hardshell carrying case for his 4G iPod. Seeing the two units merged is almost an artistic expression of aesthetic opposites, really. (The Walkman is pretty ugly.)

Have a look at Dave's colorful account of the project, complete with step-by-step photos. You might not want to try this at home....
