“The Future Piggy” Bank is project made by Wang Chao, Maggie Kuo, and Jordi Parra, at the Umeå Institute of Design, in Sweden. In just a few days, they made this mock-up of piggy bank that accepts credit cards. By using very simple components like an arduino board, a sensor and an iphone as a display, they were able to create a piggy bank which behaves like a Tamagotchi. If you don’t feed it with a credit card it will become sad and the other way around. Very nice work!
