Mad Nest is the second Parisian film by Tajiri. It is a collage-like film in which Tajiri uses different techniques and image material. A large part of the film consists of images that were created by drawing or scratching directly on the film material; these were techniques that were increasingly popular within the pre-war avant-garde.Tajiri contrasts these animation techniques with live action images: his own home movie-like recordings and found footage images. He also manipulates this footage, by colouring it, showing it in reverse or upside down, or by playing it backwards.
An important role is given to the large metal jewellery designed by Tajiri’s wife Ferdi. At the end of the film, one of Tajiri’s own welded iron sculptures makes an appearance.
