Short film director Michael Frei’s award-winning short films are known for his traditional 2D hand-drawn line animation in black and white. In a collaboration with game designer Mario von Rickenbach, he developed the short films Plug and Play and Kids into small interactive games. In the latter, the animation was assembled, composited and choreographed using a game engine with a custom-made animation system in conjunction with physics simulations. In this seminar, Michael Frei will go into the details of how he and Mario von Rickenbach worked to successfully port the project from one medium to another, focusing on solutions to the technical and artistic challenges they encountered along the way.
