Chicago's Museum of Contemporary Art store sells this stainless steel cocktail shaker that comes disguised as a graffiti-writer's spraycan — $20 for non-members, $18 for members. I'm guessing that there's a good reason for the flared shape of a traditional shaker that you lose out on by opting for this, but it's still a great novelty for your rec-room bar, to be shelved next to the peeing boy liquor dispenser and the novelty Bols liqueur bottle with the waistcoat and the monocle.
