The Bird and the Whale was created using a technique called paint-on-glass animation. Each frame is painted with slow drying oil paint and shot with a top-down camera in a light controlled room. After a frame is shot, the paint is wiped away and the next frame is repainted almost entirely from scratch. Each new frame created, destroys the last.
The full 7 minutes of animation is made up of over 4300, 24 x 34 inch paintings and took more than 14 months to paint.
