In December of a year, to send the Christmas regards to the customer, Kerve Creative, a British agent decided to do something different from traditional holiday greeting card. So, they made an interactive greeting card with Arduino. Connect the USB interface of greeting card to the computers, select MAC or PC, and then this card would be changed into a game controller with complete functions.
This Arduino drove the Christmas card to play a Christmas song. Then, the customers were invited to play the small game Hacky Xmas. They needed to use the controller to help Santa Claus cut a Christmas tree and collect game credits while avoiding the decorations falling off from the Christmas tree.
