Actually there are two interactions I would like to talk about. The first one is a website (showed by Craig in all his classes) that provides an interactive experience. As users access the website via mobile devices, they would be able to make their own paperplane, stamp on it and throw it away. Users could also catch a paperplane, unfold it, see from the stamps where this plane had been, and stamp on it. The design of this experience is quite simple and intuitive. The instructions are quite clear. What users have to do on their mobile devices really resembles what they really have to do if they are making their own paperplane.
The other interaction is from a short video I saw, between a user and a piggy bank. The piggy bank looks like a card box. As the user put the coin on the plate and press it, a cat will sneak its claw out from the box and ‘steal’ the coin away. The interaction is quite simple, but it tells a vivid story of the coin being stolen by a greedy cat.
