Meet Olly, a “web connected smell robot.”
Olly will convert tweets, Facebook notifications, RSS feeds – whatever you want – into smells:
Olly has a removable section in the back which you can fill with any smell you like. It could be essential oils, a slice of fruit, your partner’s perfume or even a drop of gin. […] Olly is stackable, so if you have more than one, you can assign each one to a different service with a different smell. Connect one to Twitter and another to your calendar. Before you know it, you’ll have a networked internet smell centre…
A slide-out tray at the rear of the device can be filled with a source for a scent – maybe essential oils or a slice of fruit. Although each Olly device can only deal with one notification smell, you can stack a number of them up to alert you to multiple different types of event with different smells.
