Here's a wonderful, charming animated short film called "Bibo." It was directed by Anton Chistiakov, and here's a story description for the moving short:
It started as an idea about a lonely robot who sells ice cream. In order to survive in a severe reality he recreates an imaginary world where he lives every day, like he did during the best time of his life.
The film is beautifully animated, and it was screened at a lot of film festivals over last year, winning many awards. I think you'll like this, so I hope you enjoy.
