diatoms

Diatoms: Unicellular water organisms (they are a type of algae) that encase themselves in a silica cell wall comprised of two valves, or shells - they come in MANY different shapes, patterns and colors! 
But diatoms are more than just pretty - they are used in forensic science to determine time of death for bodies found in water (dead before or drowned).
I think they RULE.
