Seamful design

An engaging CHI paper illustrates how to realize Mark Weiser's goal of seamful design with a game called Feeding Yoshi. The idea is to "deliberately exploit the inherent limitations of technology, rather than being hidden away". The game involves getting points by finding Yoshis and different kinds of fruits to feed them. Secured and unsecured wireless access points are used as yoshis and fruits. The fact that there is no uniform network access now becomes a location based game of hunting for yoshis and fruits, yielding a very engaging user experience.
