Fractal thingy 608
Animals in e ocean use various means to not be noticed by each other. One interesting quality of water is the fact that it allows different colours to penetrate different depths. Red light is the one that penetrates the least depth and blue the most. As a result, anything red will appear black below a certain depth (since there is no red light to reflect off of them). Other animals have lighter bellies so that if a predator is swimming below them, the belly will blend in with the lighter surface.
I don't even remember off hand what let me make these crazy shapes...but I liked swirling them around
