The
Daicon III and
IV Opening Animations are two
short,
anime,
8 mm films that were produced for the 1981 Daicon III and 1983 Daicon IV
Nihon SF Taikai conventions. They were produced by a group of amateur animators known as Daicon Film, who would later go on to form the animation studio
Gainax. The films are known for their unusually high production values for amateur works and for including numerous references to
otaku culture.
