I was a genetics major in college, then switched to organic chemistry, and I worked with fluorescence, specifically fluorescence resonance energy transfer.

I kinda hate the internet, because one of my big ideas was to try and incorporate luciferase into trees, because how badass would a glowing forest be? Maybe could even partially eliminate light use, who knows. Seems worth exploring. I think it's been done already (like Norway or Sweden), but not naturally bred into the trees genetically.

Similarly, my real million dollar idea was to come up with genetically modified cannabis that would fluoresce under black light. More of a novelty than anything. But making it bioluminescent would be interesting too. LOL, you could tell how cheesed someone is by how radiative they are. Not like it'd work like that, just a funny thought.
