Bioluminescent Toenails

I think this is self-explanatory, but here goes: cover your toenails with bioluminescent algae, allowing you sufficient visibility to your midnight journey to the toilet. As an added bonus, you won't be run over when sleepwalking down a dark street. This could take the form of a nail polish-like material to brush on, or could be injected (or otherwise inserted) into the nail at regular intervals by a physician, or someone else. The compound could be continuously alight, or could be temporarily activated with an easily accessible catalyst. I believe that some bioluminescentbacteria only glow in the presence of water so you could just get your toes wet. And you'd have an excuse to wear sandals when working late at the office.

disclaimer: Not responsible for injuries due to spontaneous, simulntaneous death of all bioluminescent bacteria.

another disclaimer: I have searched the bakery quite thoroughly for similiar ideas; if i missed one, then, in the words of St. Jerome, "Plague take those who said our wise words before we did." ( In Ecclesiasten Commentarius, I)
