Bertran sees this as a logical form of natural user interface: "I thought that a representation of a physical connection would facilitate a more intuitive interaction based on traditional mental models from the physical world." It certainly is interesting and even relatively intuitive, although the video doesn't do the heavy lifting of explaining how to develop the expansive system he's shooting for. Unfortunately, we can't imagine it would actually be all that convenient to use. It ends up looking like something from a near-future movie: visually compelling but probably impractical. That said, we'd still give something similar a try if it were ever developed.
