Olly is a scent-based system rewarding social media activity designed by Foundry, a small research team at Mint Digital. They call it a “web-connected smelly robot.”

Linking to web-based social applications, Olly emits a fragrance when you receive emails, re-Tweets, instant messages and various other pings across social channels.

Joining Olly is Molly, a robot that dispenses sweets in a similar way.
