8Bitdo's prototype Desktop Arcade Joy Stick is a) an entire retrogame cabinet, complete with controls, display and guts, b) excellently crafted from wood, c) a surprisingly beautiful re-contextualizing of the experience of play. I'd like to own an entire arcadeful of these, in sizes ranging from 6 inches to 6 feet tall, in a colossal building the exact same shape, with anarchoprimitivist propaganda and classic arcade slowruns depicted on its vast screen. The real thing, though, is perfectly desktop-sized: about 12″ across.
Sadly, it's not yet a product, though 8bitdo suggests it will become one; their store offers some gorgeously-designed retro game peripherals.
