Normipäivä was made for educational purpose to show you how NOT to handle a forklift. This video here is only a short trailer of the full length (3 minutes) movie.
Blender 3D, a free open source software, was the main program in the production. All the modelling, texturing, lighting and rendering was done within it. Normipäivä was made before Cycles was born and that’s why Normipäivä was rendered with Blender internal renderer.
Of course the bullet physics was used very much in the production to simulate all that crashing and falling.
