Ah memories. Twenty years ago I worked a few cubicles away from the guy who runs this site. He had a handmade Rube Goldberg machine made from cardboard perched on the edge of his cube wall that accepted coins as payment for candy he kept in a dish.

Was it some kind of special or expensive candy? I just give candy to my colleagues for free.

They're paying for the thrill of the cardboard contraption's operation! The candy is just the denoument.
