Ian other very interesting video . Its more likely listening lectures but with very interesting visuals . I must admire his terms and design language which seems a quite good sale skill to me as well but research is marvelous , mesmerized me on few points . Its seems not only science but geographic aspects , surrounding every thing influence and involve to create a design .Colours reflect and effect on psychology . Eye capture it and brain feel it .We might know few of them already but It still fascinating watching this .
