In the series "open source tools are amazing" Blender is one of them.
Blender is a free and open-source 3D computer graphics software toolset used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games (Wikipedia).
The latest short film produced by Blender Animation Studio and made in Blender 2.8: Spring is a marvel of poetry.
Spring is the story of a shepherd girl and her dog, who face ancient spirits in order to continue the cycle of life.
A must see!
