I completed this film just two months after finishing Playground. Drawing inspiration from optical illusions, such as Escher's paintings, I created the film using isometric drawings. My concept was to produce a compelling film relying solely on transformations of rectangular parallelepipeds. In this work, I employed the method of geometric animation, a technique previously used in Metropolis. Alongside "cell" animation, I continue to make films applying this method. Hopefully, I will eventually discover a third alternative method to use in my films.
