Hmmm. So with a hexagonal grid you would trade off a loss in information present at 0-90-180-270-360 orientations, for a compensatory gain in the intermediate rotations? I guess the best thing would be to build LCDs with pixels built this way- they could no longer display perfect verticals and horizontals, but all the rotated objects would be much more crisp. There's a new business for someone in Korea to start thinking about!
