If we can figure out some way to capture and transmit what these (and possibly other bacterial species see), we could have trillions of little cameras everywhere, possibly changing everything from medicine (deliver medical payload based of off visual information or image tumor directly without surgery) to biology (pseudo xenobiology studying the underwater volcanic mats of bacteria and algae) to even intelligence gathering (need to spy? Grow some bacteria in an air vent or other convenient area).<p>I hope that someone is starting to try and capture images from those mini eyeballs, they then become our mini bio-cameras.
