Steampunk mouse: Made from a real sheep's skull
If Lord Byron had been hip to this newfangled computer thing way back in his day, this might just have been the sort of peripheral he'd have been sporting. Made from a real sheep's skull -- and real brass, though that's somehow less interesting -- this mouse has everything a megalomaniacal world conqueror needs to feel at home: fine ornamental detailing, the soothing texture of real bone, and the enticing mental image of crushing skulls every time you click. There's not much wiggle room here, you'll either love it or loathe it, but don't fret about the sheep, it died of natural causes.
