The game “Blue Dragon” involves the hero’s shadow: the shadow turns into a giant Dragon who goes through fights and plays an important role. Using this idea as a base, we made an interactive communication where participators themselves get to control their giant transformed shadows. The program is made to transform people’s projected shadows into Dragons or to over 10 other characters in the actual game. Shadows of people moving in front of the lighted wall, are captured and processed in real-time, projecting the dragon shadow on a building wall (27 meters wide, 45 meters high) from a projector.
