Steampunk is a science fiction subculture that showcases steam-powered technology and Victorian-inspired touches to modern, working technology. Think Jules Verne or the 1999 movie, "Wild, Wild West."
Better still, Steampunk is rife with possibilities when it comes to repurposing old tech. To accomplish this, outfit your old N64 controller in a wood veneer, add copper finials to the buttons and, literally, put the on/off function under lock and key. Instead of simple pushing a perfunctory plastic button to power on, you can insert an old-fashioned skeleton key into a brass lock.
Of course, you can create a Steampunk look all your own; Steampunk caters to the customized. Try layering your controller in a brass finish. Use wood buttons. And, if you can figure out a way to actually power it using steam, that's definitely extra credit [source: Kain].
