Vending machines in Japan are amazing. First, picture a standard American vending machine, with each time of item held in a metal spiral that twists to release your item (or sometimes doesn't, as George found out with his Twix bar in the car dealership Seinfeld episode).
In Japan, there is a plastic box that mechanically moves over to your item, picks it up, and then moves down to the bottom corner for you to get your item. It's almost like a vending machine crossed with one of those claw arcade games at the shore.
I don't really want another candy bar, but I might go back just to see it in action again.
