   Playing with the idea of "different perspectives on the same story"!

     @gvy_dvpont Got me thinking… can it be done without the lens? This one seems to work!

     @gvy_dvpont Yeah, half of each pixel comes from one code and the other from the other. I assume readers sample in the center of where they expect the pixels to be based on the alignment blocks, so the important point is that the mask is the same on each pixel, and the center of the pixel lies on the boundary of the mask. So a slight shift of the picture tends to shift all of the samples to one or the other half.

     @isziaui Are you just half-toning the bits that are different? and the orientation of the sub-dots make them look more black/white based on direction? This is like 40X cooler than what I did
