Disney Applingz
The goal for this app was to have Mickey and Minnie's face on the mobile device, which would be able to perform actions like talk to the user and play mini games with them. The face would slide into a plush designed for it, to give the user the experience of being able to play with their favourite characters.
This was the only project I've ever done using Cocos2D-X which was interesting. Unfortunatly this was cancelled before it got completed for licensing issues.
