      Morning thought: 2x2 diagrams work so well because a random pair of vectors in a high dimensional space are orthogonal with probability ~1 @vgr

      Cook does an experiment. Just look at vgr's plots -- his explain just as much! There's a lot more mathematics there :D (I have a resentment towards cook's blog for doing ML on homotopy groups of spheres once because while a cool idea it just so completely misses the point...)
