Morfo is a great app that can bring the concept of hot seating way into the 21st century. Kids can take a picture of any person, animal, object and animate it. The picture is transformed into a 3d representation of the original picture with blinking eyes, a moving mouth and a protruding nose. This face moves, shows emotion, talks when you record a message and even rocks out to music! There’s a free version and a paid version available.
