Cellphone ornaments raising a stink

You know all those cellphone ornaments people like to hang off their phones, especially in Japan and Taiwan?  Now they stink.  Well, they smell.  Err, they make a smell.  Okay.  What they do, is, when someone calls, they let off a scent of your choice.  This is either a reminder that someone is calling, or it's a bizarre form of aromatherapy for people who need to be on the phone on a regular basis.  Available in fruit and food scents, like lemon, roses, and curry.  Yes, curry.
