I'll start with what is perhaps the most famous and most loved (at least internationally) of stop-motion anime short films, Dôjôji (1976, dir. KAWAMOTO Kihachirô). I tried to pick just a few still which do something to convey how awesome this animation is, but without showing the very best bits, so as not to spoil the surprise of all them. I don't think I've been very successful… They look much better when they're moving. I myself find this film particularly notable for the combined use of 2D and 3D animation in the dragon attack sequence (the dragon being 3D, while the fire is 2D and translucent – I still don't know how this was achieved) and also for the singularly powerful use of only changes in lighting (the characters' faces being fixed, like nô masks) to convey emotion, drama and foreboding.
