A very nice stylized season's greetings by Everton Schneider and Kaffe Films.
Colaborative work done with Kaffe Films. The Animation, Shaders and the render was done in Blender Cycles. The compositing was done by KaffeFilms.
People animations was done using Anima. It's not available for Blender but Cinema 4D was used as a bridge to collect motion from Anima and exported to Blender via Collada and .mdd
