Has anybody done any mods on bioluminescence? Or research on it? I was laying in bed last night pondering on how useful it would be to have. The thought that was in my head was basically a miniature light bulb that attaches to the nervous system, however that may be a bit impractical. In theory though, it could work if you used your nervous system as the electrical input; but there are oh so many unknown variables in that method.
Another possibility would be using a transdermal port, however I know many in this community are rather opposed to that. With a transdermal port though, there would be so many holes (battery, possibly light) that you may be better off just wearing a watch or the like that has a light built into it.
