Design studio HEYHEYHEY has brought us another Melvin, a Rube Goldberg machine designed to interact with it’s audience. The first one was a bit too large for any sort of real world application. Now they’ve made Mini Melvin, contained to two suitcases, who will (eventually) stamp and “write” a postcard for you. Both have a digital component that lets them interact with the people it meets. 

A really fun video, with a splendid soundtrack on top of it.
