Ricardo Maciel send us his recent work "Dengue in our history" done by the MediaTeam. The video is part of the Recife's Prefecture campaign against dengue (Pernambuco - Brazil).
It features 3D scenes with 2D animated characters telling the story of the dengue virus invasion into Brazil. They used Blender and Gimp for their production.
