rational vs intuitive

as part of my honors year ive been looking into rational and intuitive design (and the reulting conflict) ... this is by far the coolest interface ive seen in my life and it is completely intuitive. the video is about the use of interactive technology to further engage the audience at a concert (nine inch nails). interestingly, it seems that to create something so seemlessly intuitive requires a very high degree of rationality ... when setting criteria for the programs or making sure that the seperate devices involved speak the same language etc. - enough said .... watch the video.
