    Bidens VIS-UV live

    Some of my recent works on human and (simulated) insect vision, here how a flower ("black eyed susan", Rudbeckia hirta more specifically) may look like seen through a butterflies' eyes (only the sensitivity aspect: UV mapped in as blue). The stereo images are LRL images and allow crosseyed...
