画ニメ (Ga-nime) A series of experimental artistic films produced by Toei Animation in 2004-2007.

Note: The inclusion of Kono Shihai kara no Sotsugyou: Ozaki Yutaka to this list is based on the information on the now defunct page of the Toei website which lists it as Ga-nime unlike many other subsequent releases or collections.
