This amazing tribute to Hayao Miyazaki is from dono on Vimeo. He built it using Blender (3D modeling and animation), Gimp (graphics/painting creation/editing), Octane (real time 3D rendering) and Natron (matting, masking, and compositing). I will point out that all of them except Octane are free, open source software that rival any of the commercial software packages which do the same job. I am sure everyone will be surprised that the music he used is by Joe Hisaishi. It looks like he modeled and rendered the scenes, sets, and backgrounds in 3D but composited the original 2D characters into those scenes, including scenes they were never in before for some of them, creating a wonderful visual effect. Many thanks to Nerdist for the heads up on this one, and my only problem now (as someone else said in the comments) is deciding which Miyazaki masterpiece I want to re-watch tonight, after watching so many old friends on the screen together after all this time.
