it's like sunbathing under an aquarium of live bioluminescent bacteria. this is the The Symbiotic Bacterial Light Project (SBLP) by Kathy Takayama and John Nicholson. i've experimented with bioluminescent bacteria before and indeed, they are very cool. it's quite hard to keep them alive for very long in small quantities but perhaps with this quantity, it won't be a problem at all.
