Nagisa no Peppy

Two of the earliest CGI works in Japan ever made. They have the same creators as well. Nagisa no Peppy is a great step forward in pretty much every aspect, but everyone has to start somewhere. 

Two demonstration shorts about what could be done with the animation of the era, in 1932 and 1987 respectively. A staple for anyone willing to know the story of anime. 

Two late 80s 3D shorts that look astonishing for their eras. Highly recommended if you're into the history of animation. 

Two early CGI shorts, pretty well done for the era and the budget they had.
