Of your three videos here, this one is the most relevant to the contest aims, though it does not focus on a specific Physics problem. It accurately reflects the process of someone engaged in the act of discovery or innovation, and the viewer is left to wonder just what advances might come out of this person's ardent research and prototype development.
This one appears to be more pure cinematography, while the others looked more like renderings from 3-d wireframe models, using actual faces for texture maps, but it is a skillful blending of the two media - so that even a trained observer has a hard time telling where the visual elements end and the rendered ones begin, or vice versa. I hope you get to check out my contest video on the importance of the Mandelbrot Set to Physics.
You may also enjoy my performance piece honoring Zbigniev Cynkutis, who was a student of Grotowski, and tragically died in an auto accident before realizing his dream - after becoming director of the Second Studio in Wroclaw. That piece is called Encounter with Zbyczek.
All the Best,
